The U-cup N7 is a one-piece, single-acting sealing element and is available in polyurethane (TPU). U-cup seals are active sealing elements and as the system pressure increases, the force on the sealing lips also increases.
The U-cup N7 is particularly suitable for hydraulic applications and has a particularly robust design. The second sealing lip counters the stick-slip tendency. U-cup seals made of TPU are suitable for working pressures up to 40 MPa. TPU makes these seals suitable as primary and secondary seals, due to the excellent abrasion resistance.
The standard TPU compound has a hardness of 93 Shore A. Compounds in a different hardness and/or color are available upon request.
