What is Silicone Hose

Silicone tubing is a tough elastomer with high strength, flexibility, and resistance. Silicone tubing can be stretched without tearing and is highly versatile. It cannot be weakened with repeated bending and twisting due to its significant flexibility. Because silicone tubing is very hygienic and non-toxic, it can be produced as a medical-grade material, making it a popular choice for healthcare and medical applications.Silicone has properties that allow it to work well over a broad range of temperatures and adapt easily to sudden changes in weather and temperature. Silicone tubing has a major role in a variety of industries and applications involving the transfer of liquids and gasses. It has a fantastic range of properties that make it the preferred material for tubing in many situations.

Benefits of Silicone Hose

Operating Temperature Range
Silicone hoses are capable of carrying fluids at much higher temperatures than rubber. If you're building a racing vehicle or adding a turbocharger to your engine, silicone is the way to go. Our hoses have a max temperature of 350 degrees F (177 degrees C) compared to standard EPDM rubber hoses that have a max temperature of 257 degrees F (125 degrees C). That's almost a hundred degrees of difference. EPDM rubber is a synthetic rubber; organic rubber performs even worse and may soften and deform irreversibly at temperatures greater than boiling point (212 degrees F / 100 degrees C).

Flexibility and resilience
Silicone hoses have superior flexibility to rubber ones, and they maintain this flexibility over their lifespan, while rubber does not. This reduces the risk that your hoses will split, explode, harden, or become dry rotted over time.

Lifespan
Silicone hoses last practically forever and might possibly outlast your car. Because they have such a long lifespan, they can average out to a lower cost per mile compared to rubber hoses, even though their upfront cost is higher.

Weather resistance
One of the advantages of silicone tubing over rubber is that it is virtually unaffected by environmental factors such rain, snow, heat, humidity, drought, UV rays, and ozone. Rubber deteriorates faster in these conditions. This makes silicone a great choice for vehicles that will be driven in harsh environments.

Noise and vibration control
While rubber can be a source of noise due to the friction between the rubber and the mating surface, silicone has a good ability to dampen sounds and vibrations, keeping a quiet and stable profile. Incidentally, this is also a good argument for silicone hoses over aluminum ones, as the aluminum is a rigid material that must be coupled to a vibrating surface, requiring the use of a cushioning substance in the joints, and creating four sites that must be clamped rather than just two, effectively doubling your potential leak sites.

Inert material
Silicone is an extremely inert material that resists chemical reactions with other substances. Therefore, it won't corrode or adhere itself to surrounding parts like the thermostat or the crossover pipe the way rubber can. It's unlikely to bond to stems, so when you take off a hose, it's just as easy to take off as it was to put on. This makes silicone a reliable choice for vehicle applications.

What are the Applications of Silicone Hose

Silicone Tubing in the Medical Field
Silicone tubing exhibits properties that make it useful in the medical field. It has already been seen that silicone tubing is very tough, easy to clean, and easy to sterilize. Because of these properties, it is valued by medical practitioners. However, one of the most important properties that silicone tubing exhibits from a medical standpoint is its biocompatibility. This means that it is neither harmful nor toxic to living tissues and is unlikely to yield an allergic response. This makes it a popular material for medical implants, drains, catheters, feeding tubes, and other medical products that have biocompatibility as a key requirement.

Analytical Instrumentation
Silicone tubing is highly regarded for use in analytical instrumentation because of the need for flexible and sterile equipment.

Electronic Equipment and Automotive
Silicone tubing is excellent for electrical insulation, making it suitable for use in electronics across several industries. It is mostly used for insulating electrical components in automotive enclosures.

Water Filtration and Purification
Since silicone tubing is non-toxic and has a smooth inner and outer surface, it is utilized mostly in water filtration and purification systems.

Food and Dairy Processing
Food-grade silicone tubing is optimal for dairy processing equipment, beverage dispensing, and other food industry applications requiring sterile and flexible materials with high chemical and heat tolerance.

Aerospace
In the aerospace industry, silicone tubing is extensively utilized in equipment like climate control and conveyance systems. Because silicone tubing has high tensile strength, flexibility, and temperature resistance, silicone tubing is also used for vacuum seals on vehicles and aircraft.

Types of Silicone Hose

Silicone Peroxide Cured Tubing
Silicone peroxide tubing is available in a translucent format in different diameters. This type of silicone tubing mostly suits applications that do not require high purity, repeated sterilization, and critical dosing. Silicone peroxide tubing is most commonly used for different pump and transfer applications.

Silicone Peroxide Cured Tubing
These applications include automotive and industrial applications. This product can withstand temperatures as high as 392 °F (200 °C). In addition, peroxide-cured silicone tubing is more cost-effective than many other compounds. This makes it most suitable for general tubing applications.

Platinum-Cured Silicone Tubing
Platinum-cured silicone tubing has many advantages over peroxide-cured silicone tubing. These advantages make it very popular in the food and beverage industries. This type of silicone tubing exhibits a high tear strength. It can operate in a broad range of temperatures ranging from -40 °F (-40 °C) to 392 °F (200 °C). This enables the use of this product in many different applications and environments without deterioration.

Platinum Cured Silicone Tubing

Silicone Fuel Tubing
Silicone fuel tubing is most commonly utilized in the radio-controlled model car industry. This type of silicone tubing exhibits high resistance to methanol and nitro fuels, keeping the fuel cleaner and reducing the tubing's deterioration. This tubing is found in many different aesthetically pleasing colors to match any car color. It must be noted that silicone fuel tubing is designed to be used with radio-controlled model cars and is not ideal for use with petrol.

Silicone Fuel Tubing
High-Temperature Silicone Tubing
High-temperature silicone tubing is resistant to extreme temperature variations. The name of a silicone hose is typically followed by a number, like 550. This number indicates the hose's absolute maximum point of heat tolerance. Choosing the appropriate high-temperature silicone hose will be simple if temperatures are anticipated properly.

How to Choose Silicone Hose

Fit

Tubing's purpose is really quite simple: transport fluid (or gas) from point A to point B. How the tubing connects to point A and point B is important. In the human medical world, tubing connections are standardized with luers fittings and other connectors that are bonded onto the tube. These fittings make reliable connections, but they also add dead volume and cost which can make them impractical in research.

Tubing Material

Tubing material is just as important as the dimensions for a good connection. Here is how they stack up Silicone is soft and stretchy, so you can have a small inner diameter stretch over a relatively large connector which is sometimes useful if you are trying to minimize dead volume. Silicone tubing does not take a set; i.e., it will come back to its original size when pulled off the connector. However, silicone is slippery and will easily pull off connectors, so it is a poor material for friction-fit connections.

Kink Resistance

Just like your garden hose, research tubing can kink if it makes too sharp a bend. How likely it is to kink depends on the tubing wall thickness and material. Temperature is also a factor – tubing can suddenly kink as it warms up and the material relaxes, for example when body-temperature blood flows through it.

Compound Compatibility

Chemical compatibility. Certain chemical compounds or vehicles can react with the tubing material. Other compounds can stick to tubing and release later. If you are unsure, test your compound through an isolated tubing segment before starting your experiment.

Air Permeability

If fluid is static in a tube that is permeable to air, as is often the case with the exteriorized portion of a catheter, the fluid will evaporate through the tube. In the case of an exteriorized catheter this evaporation pulls blood into the tip, which can clot and lead to a blockage.

Silicone Hose Features

The tubing has good physical properties. It is flexible and can be stretched without tearing. This means that the material can be worked round and round without weakening. It is also easy to wrap up and store the tubing when it is not in use.The material is also clean and non-toxic, it is good for a broad range of temperatures and can handle sudden temperature changes.These properties make it desirable in a whole range of industrial and household applications.

Silicone tubing has other properties too that make it suitable for certain specialist functions. The material often has a translucent quality, so is often used as industrial tubing for transporting food products and powders, while giving operators some visibility of the inside of the tube.Many kinds of silicone tubing are also non-toxic and odourless, so they won't interact negatively with edible products that pass through. These tubes, which are wider than other tubes, can be used in a similar way in the medical sector.

Silicone tubing has good chemical resistance too, which means that it is easy to clean and sterilise the tubes.Smaller sized tubes are often used as cable sleeving and other electronic applications because silicone tubing has good weather, UV, radiation and ozone resistance.

Process of Silicone Hose

Extrusion Process
The extrusion process is preferred because it is cost-effective and can produce large batches of products in a very short lead time. This part-forming process is generally performed by rubber fabricators. The process is initiated when a heated and cured silicone-formulated compound is preformed into a slab or strip.

The next step is to feed the formed silicone into a screw extruder. The screw extruder forces the compound through the hardened steel die. The extruder head holds the die in place, and the die shapes the silicone tubing once the silicone has been forced through. The silicone profile then exits the die and is cured by being continuously pulled through a heated and cured oven.

Rubber Extrusion Process
Several ovens are used to circulate hot air vertically and horizontally: salt bath cures, steam vulcanization, and infrared cures. Some fabricators prefer to perform the vulcanization of the silicone after it has been extruded into a long trough filled with salt water. However, this technique has the main challenge of choosing the right raw materials that are capable of performing best in their specific temperature and mechanically controlled processes and will enable the final products to meet specifications.

How to Maintain Silicone Hose

Regular Inspection
Proactive, regular inspection is crucial to maintaining the integrity of your silicone hoses. Over time, damage can occur from the interior or exterior, resulting in small leaks that can escalate into significant problems. Inspect the hoses for bulges, leaks, hardening, or softening. When inspecting your silicone hose it's important to ensure that it is correctly stored, try store your houses hoses in a cool, dry place away from direct sunlight, extreme temperatures, and aggressive chemicals. This will prevent premature aging and keep the hoses in optimal condition for future use.

Correct Installation
Installing silicone hoses correctly is the first step towards longevity. Incorrect installation may strain the hose, reducing its lifespan and leading to premature failure. Ensure that the hoses are installed without twisting and are aligned correctly with the connections. Additionally, when using clamps, use the right type and size to prevent excessive pressure or slipping which can cause additional wear on the hose, or outright stop it from connecting as intended.

Temperature Regulation
Silicone hoses are known for their high-temperature resistance. However, this doesn't mean they're immune to damage caused by extreme temperatures. Continually exposing hoses to extreme heat or cold may accelerate wear. Therefore, try to regulate temperature conditions whenever possible to prolong hose lifespan.Despite all precautions, your silicone hoses will eventually wear out over time, thus it's important to replace your silicone hose when its lifespan has run low. Not doing so can lead to larger complications that can arise from faulty hoses, which could severely affect performance or outright stop the intended application from working at all. By regularly monitoring your silicone hose you can cut down on such complications.

Tips and Tricks for Cutting Silicone Hose

Step 1
Place the tape measure on one end of the hose and mark at the desired length. A permanent marker works well for this and will clean right off with a little bit of alcohol once you are done.

Step 2
Place your clamp straight and perpendicular to the centerline of the hose at the cut mark. Make sure that the clamp band is the same distance from the end of the hose at multiple points on the hoses circumference. Tighten the clamp onto the hose.Setting Clamp for Silicone Cut

Step 3
Double check that the clamp is set at the correct measurement. Insert the point of the blade through the outer wall of the hose using the clamp as a guide. Once you have penetrated through the wall of the hose, slide the blade along the edge of the clamp until you complete the cut. (If using just a liner clamp you may need to remove the clamp before finishing the last 1/2" of the cut where the clamping block is.)Cutting Silicone Hose

FAQ

Q: Why a silicone hose?

A: There is a growing trend that silicone hoses are replacing rubber hoses in some applications around extreme temperatures. Silicone hoses show good performances within extreme temperatures. At higher temperatures up to 300°C, it will not be excessively softening; under below zero it will not become rigid. However, black rubber hose will fail when working at continuous high temperatures. Further more, coolant, water and extreme temperatures all can cause hose deterioration. Rubber particles loose from the hose wall will cause clogged radiators, heater cores and thermostats. Hence, the best and the easiest way to solve this problem is to replace the black rubber hosed with silicone hoses.

Q: The Thicker, the better?

A: A thicker hose is often mistaken for a good one. In fact, it is the reinforcement that determines the tensile strength/temperature rating. Thicker hoses over 4 plies reinforcement add no value in burst pressure, heating rating, etc. unless the same reinforcement is employed. Thick hoses made of low quality raw materials should be manufactured thicker for holding their shapes or forms. Leak issues often happen to thick silicone hoses. In addition, thick hoses are not so pliable, which makes them difficult to install. Many manufactures use polyester fabric, aramid, Nomex and nylon instead of fiber glass which is idea for working under very high temperature and high pressure conditions.

Q: What is the appearance of high-quality silicone hose?

A: Obviously, it is a silicone hose with 4-ply polyester fabric. There are two drawbacks. First, the fabric begins to come off. Second, both of the outside and the inside are made of different materials.
Generally speaking, a qualified silicone hose should be smooth. Obviously, this wrap finish makes it unqualified and not suitable for usage.
One of products - straight reducer by 4-ply polyester, has a trim cutting, smooth finish and the material of inside and outside are coincident.
When selecting a silicone hose, the method of distinguishing high-quality silicone hoses from low-quality ones is spot its appearance. First, good silicone hoses should have a smooth finish, while the "wrap" should be as minimal as possible. Second, the layers of both inside and outside should be made of the same quality materials. Two different materials are used to reduce manufacturing costs and performances as well. Third, first-class silicone hoses should show a deep color and not a dull appearance. The image above is a model of our products. Smooth finish, deep color and the outside and inside layers share the same color prove it a qualified silicone hose.

Q: How do I cut universal silicone hoses?

A: To get a trim cutting, there are two points for your special attentions. First, make sure that the hose be placed horizontally. Second, tighten a clip around the hose without deforming the hose. Then guided by the edge of the clip, you can cut the desired length with a sharp knife. However, the place near worm drive section is not available for cutting, for it is not even there.

Q: How do I clean silicone hoses?

A: Rubbing alcohol, soap or WD-40 with warm mater will be suitable for wiping the hoses. For grease marks, WD-40 is very effective.

Q: What is the right way of storing hose?

A: Storage has an important pact on the life span of hoses, new or used hose stored between jobs. Generally, hoses should be stored in flat oil on the floor, a shelf or a table. If hose is non-reelable, keep it in straight lengths. The environment for storage should be cool, dark, clean and with good ventilation.

Q: How to select the right hose for particular applications?

A: We have got a simple principle for selecting the right hose: S.T.A.M.P.E.D.
S stands for SIZE; I.D., length and sometimes OD.
T stands for TEMPERATURE of the material conveyed and environmental
A stands for the APPLICATION, the conditions of usage.
M stands for the MATERIAL being conveyed, type and concentration
P stands for the PRESSURE to which the assembly will be exposed
E stands for ENDS; style, type, orientation, attachment methods, etc.
D stands for DELIVERY; testing, quality, packaging, and delivery requirements
Especially for selecting a silicone hose, working environment and materials being convey should be considered. Silicone hoses are often reinforced by different materials, each of which has different properties. Broadly speaking, polyester can be suitable for most applications. However, Nomex is preferred to higher temperature than polyester. When contacting with oil and fuel, the former two hoses can't work. Fluoro lined silicone hose is especially engineered for carrying oils for its low permeability.

One of the decomposition products is silicon dioxide, also known as silica. question that Viper Performance are frequently asked is “can I shrink or stretch the diameters of silicone hoses if I buy the wrong size?” The answer is simple “no.”

Q: Are expandable hoses better than rubber?

A: As a veteran gardener, I love expandable hoses. They're light, agile and kink-free. The Flexi Hose maneuvers around obstacles with ease and is less likely to damage plants in its wake than a heavy rubber hose.Well standard silicone hoses are porous and therefore not suitable for oil or fuel. There are flurosilicone liners, which are specially formulated to prevent oil from penetrating the wall but we would not recommend these for Fuel lines, or heavy use of Fuel Filling.

Q: Is a polyurethane hose better than a rubber hose?

A: Durability. Polyurethane hose is made of the same material as the wheels on in-line roller skates and is strong enough to withstand potential damages like being pulled across rough or sharp surfaces. The outer cover on the rubber hose is much softer and can tear easily.While using your hose to water plants, fill water balloons, or run your sprinkler are all great ideas, many don't meet the safety standards required for drinking water. They can contain lead or be made from materials that leach chemicals into the water, especially when heated by the sun.

Q: Which is better rubber or PVC water hose?

A: PVC hoses are known for their light weight, flexibility, and resistance to chemicals and UV radiation. In summary, rubber hoses are typically stronger and more durable, while PVC hoses are usually lighter, more flexible, and more resistant to chemicals and UV radiation.If you're looking for a clamp that has both strength and durability to ensure your silicone tubing stays where it's supposed to be, then you should check out these 100% stainless steel t-bolt hose clamps.

Q: Is all silicone hose the same?
