DanaFlex H Static R63

DanaFlex H Static is designed for high sealing efficiency, even in cryogenic applications.
It consists of a PTFE-based material activated by a AISI 316L stainless steel spring with high chemical resistance. The spring is helical, which maximises the spring force.
Thanks to this design, it has durable elasticity throughout the lifetime, regardless of medium, temperature and application.
