100000 O-Ring Seals Shipped To Germany

100,000 O-Ring Seals Successfully Shipped from Xiamen Jinshun Sealing to Germany

[2026-09-28] | By Xiamen Jinshun Sealing Technology Co., Ltd. Annie Xu ywb6@jinshunxm.com

Xiamen Jinshun Sealing Technology Co., Ltd. has successfully completed the production and shipment of 100,000 O-Ring Seals for a customer in Germany. The supplied O-Rings measure 7.59 × 2.62 mm, with the completed order packed into 65 cartons for export shipment.

This shipment is a straightforward example of the type of volume production required when an O-Ring becomes a production component rather than a small replacement part.

The 7.59 × 2.62 mm specification identifies a relatively small precision sealing component, where dimensional consistency matters because a small change in cross-section can affect installed compression and sealing contact.

Jinshun's production work covers standard and custom O-Rings for industrial equipment, water-related products, sanitary products, electronics, machinery and automotive applications. The company's current O-Ring manufacturing range also includes standard and custom sizes for different sealing requirements.

For an O-Ring Seal, the nominal dimensions are only part of the engineering requirement. The finished part must also maintain consistent cross-section, diameter, surface condition and molding quality from one production batch to the next.

For a 7.59 × 2.62 mm O-Ring, the 2.62 mm dimension represents the nominal cross-sectional diameter. During assembly, that cross-section is compressed inside the sealing groove to generate contact pressure.

If the cross-section is too large, installation force and compression can increase. If it is too small, sealing contact may be insufficient.

This is why O-Ring production requires dimensional inspection rather than relying only on visual inspection. Jinshun's published quality-control process includes appearance, dimensional, pressure, media-resistance, air-tightness, hardness, tensile, elongation, tearing, compression-deformation and aging checks where applicable to the product specification.

Key Engineering Parameters for an O-Ring Seal

For engineers developing a new component, groove dimensions should be reviewed together with the O-Ring specification. Jinshun's engineering guidance also emphasizes that leakage problems can originate from incorrect groove dimensions or compression rather than simply from the rubber material itself.

A 100,000-piece order requires more than molding the required number of parts. Production control has to remain consistent across the complete manufacturing batch, while packaging must keep the parts protected during handling and international transportation.

For a production O-Ring Seal order, the manufacturing workflow can involve:

Material specification
The elastomer and compound are defined according to the application.

Tooling and mold preparation
Mold dimensions are matched to the approved O-Ring geometry.

Rubber molding
The compound is processed into the specified O-Ring dimensions.

Deflashing and finishing
Excess rubber and unacceptable molding defects are removed.

Dimensional inspection
Critical dimensions are checked against the approved specification.

Physical and performance testing
Hardness and other specified physical or sealing tests are performed as required.

Sorting and packing
Approved O-Rings are counted, packed and prepared for export.

Carton shipment
The finished order is packed into export cartons for international delivery.

The exact inspection and packaging plan depends on the customer's drawing, material specification, quantity and quality requirements.

At high production quantities, batch consistency becomes just as important as the performance of an individual O-Ring.

For purchasing and QA teams, useful production controls include:

Xiamen Jinshun Sealing Technology Co., Ltd. was established in 2002 and operates with ISO 9001:2015 and ISO 14001:2015 management systems. The company manufactures rubber O-Rings, Y-seals, shower gaskets, RO membrane seals, silicone tubes and other customized rubber sealing components.

The company states that its raw materials meet applicable RoHS, REACH and PAHS requirements, with many products available with certifications or approvals including NSF, FDA, LFGB, ACS, KTW-W270, WRAS and UL, depending on the material and application.

Image Suggestion

The German shipment is one example of a larger production model: customers provide a required O-Ring specification, and the manufacturer converts that specification into a repeatable molded rubber component.

For international importers, distributors, equipment manufacturers and procurement teams, a useful O-Ring purchasing specification should include:

• O-Ring ID
• O-Ring cross-section
• Material
• Hardness
• Operating temperature
• Sealing medium
• Working pressure
• Static or dynamic sealing
• Required standard
• Quantity
• Packaging requirement
• Inspection requirements

Jinshun's current O-Ring manufacturing offering covers both standard and customized O-Rings, with production and inspection capabilities for different industrial sealing applications.

For buyers working from an existing drawing, the fastest way to start is to provide the drawing, sample or exact O-Ring dimensions together with the operating conditions.

For an equipment manufacturer or distributor, an O-Ring is usually a small component, but its failure can stop an entire assembly from passing leak testing or entering production.

That makes repeatability important at volume.

A production order such as 100,000 pcs of 7.59 × 2.62 mm O-Ring Seals requires the supplier to control the approved material, mold dimensions, production process, inspection criteria and packing quantity throughout the order.

For international sourcing teams, these controls also make supplier qualification easier because the purchase specification can be connected directly to incoming inspection.

Jinshun supports international customers with OEM and ODM sealing production, including custom O-Rings and molded rubber components. Its manufacturing background covers water treatment, food and drinking-water equipment, sanitary products, electronics, machinery and automotive applications.

The completed shipment consists of:

For buyers sourcing custom O-Ring Seals, metric rubber O-Rings or high-volume molded rubber sealing components, the same production approach can be applied to new specifications.
