Sell PTFE glyd seals, step seals

Description

Properties 
Bidirectional seal ring for pistons. Composed of a PTFE-Bronze wear-resistant ring and an O-ring. With its elasticity, the O-ring can offer compensation for the wear of the PTFE ring and a bidirectional sealing. Applied to the sealing of hydraulic cylinder piston with pressure on both sides. Usually used with guide rings.
