When your hydraulic system demands a seal that can handle pressure, motion, and durability-all while resisting wear and fluid degradation-you need a V Type Seal you can trust. At Xiamen Jinshun Sealing Technology, we've been engineering high-performance V-ring seals since 2002 from our ISO 9001 & ISO 14001-certified facility in Xiamen, China. Whether you need standard sizes or fully custom V Type Seals in NBR, EPDM, silicone, or other compounds, we stock over 40,000 dimensions and deliver globally with full certifications like NSF, WRAS, KTW, FDA, and RoHS.
What Is a V Type Seal?
A V Type Seal-also called a V-ring seal or V-shaped sealing ring-is a flexible, wedge-shaped rubber seal designed for reciprocating motion in hydraulic cylinders, pumps, valves, and other dynamic equipment. Its unique V-profile compresses under pressure, creating a tighter seal as system pressure increases. That's why it's a go-to choice in industries like automotive, machinery, food processing, and water systems where reliability matters.
Unlike flat washers or O-rings, V seals excel in high-pressure, low-speed applications and can be stacked for even better performance (called a "V-packing set").

FAQs
Q1: What's the difference between a V Type Seal and an O-ring?
A: O-rings are circular and static/dynamic in low-pressure systems. V Type Seals are designed for high-pressure reciprocating motion-like hydraulic rams-and can handle misalignment better. Plus, you can stack multiple V-rings for enhanced sealing.
Q2: Can I get samples before placing a bulk order?
A: Yes! For standard sizes, we ship free samples within 3–5 days. For custom V Type Seals, a small prototype fee may apply-but it's credited back on your first production order.
Q3: Do your V seals work with drinking water or food-grade applications?
A: Absolutely. Our EPDM and silicone V Type Seals are certified to NSF/ANSI 61, WRAS, KTW, W270, and FDA-making them safe for potable water, food machinery, and sanitary equipment.
Q4: What testing do you perform on your rubber seals?
A: We run full in-house testing:
- Physical: Hardness (Shore A), tensile strength, compression set, elongation
- Chemical: Material composition (e.g., silicone purity), fluid resistance
- Certification-based: NSF, WRAS, RoHS compliance checks
All reports available on request.
Q5: Are you a factory or trading company?
A: We're a real manufacturer-founded in 2002, 12,000㎡ factory in Xiamen, with R&D, production, and export teams under one roof. No middlemen. Direct pricing. Full traceability.
