Piston Seals

CAPPED T-SEAL

Capped T-Seals are similar in function to that of a normal T-Seal, except the elastomer energizes a PTFE cap that seals the dynamic  surface. Since the PTFE cap is made a low friction material, capped T-Seals are well suited as heavy duty piston seals in high duty cycle linear actuators. Low friction also means low wear, which provides excellent long term life capability.

O-Ring Loaded

This dual action piston seal is designed for applications where maximum sealability is required. More

ASYMMETRICAL UNLOADED U-CUP

Asymmetrical Unloaded U-Cup

The asymmetrical unloaded U-Cup is designed to have both a static and a dynamic side. More

GROOVED

Grooved

Grooved seals are bi-directional seals that are specially designed to deal with a wide range of sealing pressures. More

SYMMETRICAL U-CUP

Symmetrical U-Cup
