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.
