Piston Sealings

Piston seals are active sealing components that are used for external sealing applications in hydraulics and pneumatics. Piston seals are produced in different variants. Piston seals are predominantly used in dynamic and linear movement applications. The sealing function is supported by the acting system pressure.

Gleitef

Gleitef is a double acting sealing element which consists of a PTFE seal and an o-ring as preload element. PTFE sealing elements are produced by machining and can be produced for almost every specific installation space and diameter. Application range for hydraulic and pneumatic cylinders and machine tools.

Stuftef

Stuftef is a single acting sealing element which consists of a PTFE seal and an o-ring as preload element. PTFE sealing elements are produced by machining and can be produced for each specific installation space and diameter. Application range for hydraulic and pneumatic cylinders and machine tools. Also suitable for tandem arrangements.
