SEAL - UCUP (Hyster HY0322570)

A worn u-cup seal can allow fluid leakage past the sealing surface, reducing system pressure and causing erratic operation. This aftermarket replacement part references Hyster catalog number HY0322570. The u-cup seal functions by using its lip to create a dynamic barrier against fluid escape along a reciprocating rod or piston. Over time, the seal material can harden or crack, leading to external drips and gradual loss of performance. In a typical application, the seal is installed in a gland or housing to contain pressurized fluid during linear motion. Verify the serial number or application, then call (562) 693-7748. The part is a seal type commonly used in fluid-power components.
