PTFE gasket CMD-1019 series

compressionfitting

Cold flow is the term we use for movement of plastic under permanent load/stress, a state that is used with static seals. Cold flow increases at elevated temperatures. Material of the gasket is slowly moving towards the inside of the fitting and creates a bead. This bead leads to flow restriction and is a potential area for particles/bacterial entrapment. The Steam-Flon® material takes the cold flow out of the equation, creating a very stable seal with no leaks even at large temperature fluctuations. For Steam-Flon material the specification is Deformation under Load 14 MPa - 24 hrs @ 23°C = 5% ​ For standard PTFE it is: Deformation under Load 14 MPa - 24 hrs @ 23°C = 15% Steam-Flon® is a registered trademark of Ultrapharma BV Recommended Torque The Steam-Flon® gasket last longer if the correct torque is applied. Over-compression is disastrous for each gasket material, even for Steam-Flon®. We came to these recommendations after testing our gaskets at 10 bar water pressure.
