High Temperature Gaskets

Custom gaskets cushion and seal spaces between components while protecting against extreme temperatures.

Custom gaskets for high temperature applications made from materials that can withstand temperatures exceeding 350 degrees.

High temperature materials deliver reliable performance in both severe cold and extreme heat, prolonging the life of components, while making them run more efficiently. We can die-cut these materials and convert them into custom shapes to meet your requirements.

Common High Temperature Gasket Materials


400°F (260°C) – Silicone materials offer resistance to temperature extremes, UV and ozone, extremely resilient to mechanical fatigue, excellent compression-set and creep resistance and are compliant with the most stringent UL flame ratings.


400°F (260°C) – Fluorosilicone materials are flexible, compressible and designed for use in extreme temperature ranges with excellent weatherability, compression set resistance, electrical strength and non-stick properties.

Fluoroelastomer (Viton®)

500°F (260°C) Viton® materials offer excellent chemical resistance, excellent weatherability and ozone resistance, excellent gas and liquid permeation resistance, good mechanical properties, improving sealing performance.

Compressed Aramid Fiber

700°F (371°C) – These materials are typically resistant to oils, water, steam, gases, salt solutions, fuels, alcohols, moderate organic and inorganic acids, hydrocarbons, lubricants, and refrigerants.


392°F (200°C) – Nomex® delivers exceptional thermal stability, mechanical toughness, dielectric strength, flame resistance and a broad chemical compatibility.

Teflon™ PTFE

500°F (260°C) – Teflon™ has many advantages including chemical resistance, dielectric properties, low friction, no embrittlement or aging, waterproof, corrosion resistance, high thermal stability and flame resistance and resistance to weathering.


High-temperature gaskets are used in a wide variety of industrial and consumer electrical and electronic applications as electrical insulation and thermal insulation. Product applications include:
Oil & Gas
Utility Services
Food & Beverage
