Gleitef KW is a double-acting sealing element which consists of a polyurethane (TPU) seal and an O-ring as preload element. Gleitef KW is an active sealing element and as the system pressure increases, the force on the sealing edges also increases. Due to the special geometry of Gleitef KW, the blow-by effect is prevented during double-sided pressurization.
This is particularly suitable for hydraulic cylinders, agricultural machinery, lifting equipment and machine tools. TPU is characterized by its excellent abrasion resistance and can also be used with insufficient lubrication. The standard TPU mixture is produced with a hardness of 93 to 96 Shore A and is available in different colors. O-rings are available in all standard materials.
