O-RING (Nissan NICK25K040120)

A worn O-ring can allow fluid or air to bypass the sealed joint, reducing system pressure and causing erratic operation. During routine service, an O-ring that feels brittle or shows compression set should be replaced immediately. This aftermarket replacement part references Nissan catalog number NICK25K040120. The O-ring functions as a static seal between two mating surfaces, preventing leakage under normal operating pressures. A common failure consequence is gradual weeping that accelerates into a steady leak if left unaddressed. Keeping a sealing component in sound condition helps maintain consistent performance in pressurized circuits. Verify the serial number or application, then call (562) 693-7748.
