CUP 3,00X0,75 (Mitsubishi MB0A3717)

MB0A3717: A damaged cup can allow fluid bypass, reducing system pressure and causing sluggish operation. During inspection, a cup that is cracked or worn may lead to internal leakage and loss of prime. Keeping a cup in sound condition helps maintain consistent sealing within its bore. The aftermarket replacement cup references Mitsubishi as the OE maker and cross-references part number MB0A3717. This cup type serves as a sealing component that prevents fluid from escaping between two mating surfaces. A common failure consequence is gradual performance drop due to insufficient seal compression. Verify the serial number or application, then call (562) 693-7748. The catalog spec is 00X0.
