China Rubber Gaskets Suppliers - Flat Washer Seals, Rubber Spacers & Washer Rubber Rings from a Reliable Factory
Hardness
The Shore A hardness ranges from 25 to 95 degrees and can be customized according to specific needs.
Applicable Temperature Range
It ranges from -40°C to 120°C. For special rubber materials, this range can be extended to from -80°C to 300°C.
Characteristics
It has good flexibility, sealing performance, shock absorption ability, and electrical insulation property. It can effectively fill the gaps.
Application Scenarios
Suitable for pipeline connections, bathroom fittings, and mechanical component combinations. Widely used in food, drinking water, bathroom fixtures, sanitary ware, automobiles, gas, electronics, chemical engineering, aerospace, hardware machinery, and pneumatic/hydraulic systems.
Main Materials of Rubber Gaskets
The main materials of rubber gaskets include: silicone rubber gaskets, nitrile butadiene rubber (NBR) gaskets, ethylene propylene diene monomer (EPDM) rubber gaskets, peroxide-cured EPDM rubber gaskets, fluororubber (FKM) gaskets, and other rubber gaskets.
Silicone rubber has outstanding high and low temperature resistance. It can maintain good elastic performance within the temperature range of -70°C to +260°C. It is resistant to ozone and weather aging, making it suitable as a sealing gasket in bathroom fixtures, automobiles, and thermal machinery. It is non-toxic and can be used to make thermal insulation, electrical insulation products, and medical rubber products. Meanwhile, it also has excellent properties such as water resistance, flame retardancy, high temperature resistance, electrical conductivity, wear resistance, and oil resistance. The silicone gaskets produced by our company meet the EU environmental protection standards and EU food-grade standards.
Profiled Gaskets & ED Rings
There is a wide variety of profiled gaskets. Among them, the relatively standardized ED ring is one of many industrial seals. As a special seal for pneumatic and hydraulic connectors such as pipe connectors, hydraulic plugs, and transition connectors, it has a better sealing effect than the traditional O-ring. This elastomeric seal is used as an axial static seal, applied to threaded oil ports and screw ends. The cross-section remains almost constant even under high pressure.

Frequently Asked Questions
What other names are rubber gaskets known by?
Rubber gaskets are also commonly referred to as Flat Washer Seals, RUBBER SPACERS, or washer rubber rings.
What is the standard hardness range for rubber gaskets?
The standard Shore A hardness ranges from 25 to 95 degrees. This can be fully customized depending on your specific application requirements.
What are the temperature limits for silicone rubber gaskets?
Silicone rubber gaskets exhibit outstanding temperature resistance, maintaining excellent elasticity within a wide temperature range of -70°C to +260°C.
What are the key advantages of ED rings over traditional O-rings?
Compared to standard O-rings, ED rings feature minimal mechanical deformation of the cross-section, prevent relative movement during pressure cycles, maintain reliable long-term sealing performance, and can withstand working pressures up to 60 MPa.
What industries commonly use rubber gaskets?
They are widely utilized in food processing, drinking water systems, bathroom and sanitary ware, automotive, gas, electronics, chemical engineering, aerospace, hardware machinery, and pneumatic and hydraulic systems.
Do your silicone gaskets comply with food safety standards?
Yes, the silicone gaskets produced by our company comply with both EU environmental protection standards and EU food-grade standards, making them safe for food and medical applications.
