High Temperature Seals - Including Kalrez® Seals

Supplied in the UK by Orinoco Bearings

High temperature seals are now available in the UK. Kalrez O-Rings ( manufactured by the DuPont Corporation USA ) can now operate in temperatures up to 327*C and are available in a variety of different grades such as 4079, 6375 and 7075 etc.

Viton O-Rings ( also manufactured by the DuPont Corporation ) are widely available commercially in both Imperial and Metric sizes and offer an upper working temperature of 200*C.

Other manufacturers offer O-Rings that are direct equivalents to DuPonts Kalrez and Viton and these can often work out cheaper and be more readily available. If you have a requirement involving a high temperature O-Ring then talk to us - we have a solution.
