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