Stuftef SR is a single-acting sealing element which consists of a polyurethane (TPU) seal and an O-ring as preload element. Stuftef SR is an active sealing element and as the system pressure increases, the force on the sealing edge also increases.
Due to the excellent abrasion resistance qualities of TPU, makes the Stuftef SR particularly suitable as a secondary seal in a redundant system. The standard TPU blend has a hardness of 58 Shore D. Further materials 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.
