THERMa-PUR® Extreme Heat Gasket Material

Corrosion-resistant THERMa-PUR is the only gasket material designed to withstand high pressure and temperatures up to 1,832°F / 1,000°C.
Trusted for use in rocket boosters, THERMa-PUR takes on conditions that graphite cannot. This high-performance gasket material maintains an effective seal during pressure and temperature fluctuations, with excellent torque retention for lower leakage rates and less maintenance time.
THERMa-PUR’s is hydrophobic and resists water absorption and oxidation, keeping metallic gaskets in shape for a longer-lasting seal. When it’s time for removal, THERMa-PUR prevents gaskets from sticking to flanges, making removal easy and fast.
