Description
The Durapipe FPM Stub Flange Gasket is designed to create a secure, leak-free seal within flanged Corzan CPVC pipework systems. Installed between the stub flange face and the backing ring assembly, it ensures consistent sealing performance even in demanding industrial environments.
Manufactured from high-quality FPM, this gasket offers excellent resistance to aggressive chemicals, solvents and elevated temperatures, making it the preferred choice for corrosive process applications where EPDM is not suitable. Its resilient construction allows it to maintain sealing integrity under pressure and thermal variation.
Designed specifically to match Durapipe CPVC stub flanges, the gasket integrates seamlessly into PN and ANSI flange assemblies when used with the appropriate backing ring and bolting arrangement.
