DanaFlex V Dynamic Reciprocating P606/P607

DanaFlex V Dynamic Reciprocating is designed for high sealing efficiency of semi-dynamic applications.
It consists of PTFE-based materials activated by V-shaped stainless steel springs, which provide good spring force as well as high flexibility. It has durable elasticity, regardless of medium, time, temperature and application.
Dana Flex V Dynamic Reciprocating is even available in a Hi-Clean version for filling the spring groove with FDA-approved silicone, which makes cleaning of the seal very easy.
