DanaFlex V Dynamic Reciprocating R616/R617

DanaFlex V Dynamic Reciprocating is designed for high sealing efficiency in semi-dynamic applications. It consists of a PTFE-based material activated by a V-shaped stainless steel spring, which provides a good spring force as well as high flexibility. It has durable elasticity throughout the lifetime, regardless of medium, temperature and application.

DanaFlex V Dynamic Reciprocating is also available in a Hi-Clean version, where the spring groove is filled with FDA-approved silicone to ensure an easy-to-clean seal.
