Product selling points

PTFE Gasket | Rubber Gasket

Ring Gasket 

Spiral wound gasket 

Made of high-quality synthetic rubber raw materials such as NBR, EPDM and FKM, integrally molded by compression molding, with smooth surface and no burrs, customizable in various sizes and hardness (20-90 Shore A), complying with FDA food-grade standards and ISO 9001 quality certification.

Excellent elasticity, strong compression and deformation resistance, can closely fit the sealing surface, fill tiny gaps, have good oil resistance, aging resistance, ozone resistance and acid-base resistance, easy to install, suitable for static and dynamic sealing scenarios, not easy to fall off or crack.

Effectively prevent liquid and gas leakage, eliminate equipment failures and potential safety hazards, reduce maintenance costs and downtime losses; suitable for chemical, automotive, water treatment, food and other industries, with long service life and high cost performance, which can reduce the frequency of gasket replacement and improve production efficiency.

Solid metal structure (octagonal/oval), metal-to-metal line/area contact sealing
Radial self-tightening effect; higher pressure = tighter seal
Zero leakage risk, ensures permanent & reliable sealing under extreme conditions.

Premium materials (304/316/Ti-alloy/Inconel), withstands -200℃ to 1000℃
Resists up to 100MPa ultra-high pressure, far superior to rubber/gasket
Ideal for petrochemical, oil & gas, nuclear, boiler; ensures stable long-term operation

Stainless steel/special alloy, resists acid, alkali, sour, chlorine & seawater corrosion
No aging, no deformation, reusable; 5–10× longer life than rubber gaskets
Greatly reduces replacement frequency, cuts maintenance cost & downtime risk

Precision CNC machining, tolerance ≤0.02mm, meets ASME B16.20 ...
Hardness 15–20HB lower than flange, protects flange & ensures perfect fit
Ready to install, fits R/RX/BX flanges, strong universality

Made of stainless steel, carbon steel or nickel alloy thin strips wound spirally, alternately filled with graphite, PTFE or ceramic fiber fillers, equipped with centering ring and inner ring, high temperature resistance up to 540℃, high pressure resistance up to 160bar, complying with international industrial sealing standards, customizable in various specifications.

Solid structure, strong blow-out resistance, combining the rigidity of metal and the flexibility of filler, can adapt to tiny deformations of the sealing surface, high sealing precision, wear resistance, aging resistance, suitable for scenarios with frequent pressure fluctuations, accurate positioning during installation, not easy to shift.

Suitable for high-pressure and high-temperature scenarios in heavy industries such as electric power, petroleum, natural gas and aerospace, effectively prevent leakage of high-risk media, ensure long-term stable operation of equipment, and reduce the number of shutdown inspections; service life is much longer than ordinary gaskets, reducing replacement costs and labor costs, and improving the safety and efficiency of industrial production.
