Extruded Silicone Seals

Extruded Silicone Seals

Extruded silicone rubber seals & gaskets provide outstanding high and low temperature resistant properties. Extruded silicone is very resistant to deteriorating effects such as ozone, electrical current, weathering and radiation. Under normal operating conditions temperatures as high as 500°F/260°C and as low as -150°F/-101°C can be achieved with extruded silicone.

The estimated useful life of silicone rubber is shown in the table to the right. Useful life is defined here as the period of time during which the rubber retains an elongation of 50% or more. Oven and dryer access panel and door seals can be installed easily using seals from our wide variety of profiles. Silicone seals and gaskets are an affordable, long lasting option for your high or low temperature application. Choose tadpole, “e”, flat, round, and “U” shaped designs. Most are in stock and ready to ship! Custom designs are also available.
