CUP 2,25X0,58 (Mitsubishi MB0801992)

A damaged cup seal can allow fluid bypass, reducing system pressure and causing sluggish operation. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB0801992. The cup functions as a sealing component, typically installed in a bore to prevent leakage between moving surfaces. Its plain mechanical role is to maintain a static or dynamic seal under compression. A common failure consequence is gradual loss of sealing force, leading to external drips or internal cross-port leakage. The listed spec is 25X0. Verify the serial number or application, then call (562) 693-7748.
