A PTFE sealing ring energized by an O-ring is designed for bi-directional pressurization, pneumatic pistons, such as in control cylinders, in quick acting cylinders, and servo-assisted equipment. It is dedicated for assembly on an integral piston to serve as a high extrusion resistance but very low sliding friction sealing in pneumatic applications.

Pressure: ≤16BAR
Temperature: -60~+200ºC
Speed: ≤4m/s
Material: Bronze filled PTFE
