Rubber Gaskets

A: Rubber gaskets seal mechanical interfaces by filling gaps, preventing liquid/gas leakage while providing shock absorption. They're widely used in pipelines, machinery, automotive, and other applications.

A: Reusing rubber gaskets is generally not recommended, especially in high-pressure/high-temperature or dynamic sealing scenarios due to aged-induced performance degradation. Low-load static seals (e.g., household pipes) may be reused short-term if undamaged and non-aged, with leakage risks assessed.

A: Some rubber materials are oil-resistant, such as nitrile rubber (NBR), fluororubber (FKM), and hydrogenated nitrile rubber (HNBR), making them suitable for oil-contact applications. In contrast, EPDM and silicone rubber are non-oil-resistant and prone to swelling or failure when exposed to oil, so they should be avoided in oil-based environments.

A: To extend a gasket's lifespan, you should ensure proper installation (avoid over-tightening or under-tightening), store it in a cool, dry place away from heat and chemicals, and regularly inspect and replace aged gaskets promptly.

A: To determine if a gasket needs replacement, you can inspect for surface cracks, hardening, softening, or swelling; check for liquid/gas leakage at the interface; and look for performance issues like poor sealing or gasket displacement.

A: Of course, samples are free of charge; however, shipping costs will apply.

A: The sample lead time is 3 to 15 days.

A: The delivery time is approximately 10 to 30 days after order details and production are confirmed.
