Why Loaded U-Cups Excel in High-Pressure Sealing Applications High-pressure hydraulic and pneumatic systems place demanding requirements on sealing elements. As pressure rises, a seal must maintain contact with the mating surface, resist extrusion, tolerate repeated movement, manage friction, and survive exposure to temperature and hydraulic media. Among the sealing profiles designed for reciprocating applications, the U-Cups seal is widely r/ecognized
