Piston Seals
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.
Varitef
Varitef is a single acting sealing element which consists of a PTFE seal and a stainless steel spring as preload element. Due to the materials, it can be sterilized to make it particularly suitable for valves and pumps, and for dosing devices in food and medical technology.
U-cup
The U-cup is a single acting one-piece sealing element made of elastomer or polyurethane. They are particularly suitable for hydraulic and pneumatic applications as a primary and/or secondary sealing.
