O-RING - CONVERTER (Nissan NI22R51-03211)

A damaged converter O-ring can allow fluid leakage, reducing system pressure and causing erratic operation. This aftermarket replacement part references Nissan as the OE maker and cross-references part number NI22R51-03211. The O-ring creates a static seal between mating surfaces in a converter assembly. Its plain mechanical function is to prevent fluid bypass under compression. A common failure consequence is gradual loss of sealing integrity, leading to visible drips or wetness around the joint. During routine service, a hardened or cracked O-ring may indicate age-related deterioration. Verify the serial number or application, then call (562) 693-7748.
