Identify cylinder sealing components and learn what they do.

High-Speed Piston Seals


	Profile

PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

High-Stability High-Speed Piston Seals


	Profile

A square O-ring prevents these piston seals from rocking in the groove. They have a slippery PTFE surface that allows rod speeds more than two times faster than our other piston seals.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
