Gleitef SF is a double-acting sealing element which consists of a PTFE seal and an O-ring as preload element. Gleitef SF is an active sealing element and as the system pressure increases, the force on the sealing edge also increases. Gleitef SF requires a much small installation space than Gleitef SG and is used for applications with limited space and lower pressures.
The PTFE compound is filled with a special filler or with carbon graphite to improve the compressive strength. Further compounds upon request. O-rings are available in a variety of different materials. This is particularly suitable for hydraulic and pneumatic cylinders, fittings, presses and machine tools.
