O-RING - HYDRAULIC UNIT (Hyundai HN0634-313-395)

A damaged retaining ring can allow hydraulic unit components to separate under pressure, leading to sudden fluid loss. During disassembly, a worn O-ring may fail to seal, causing gradual leakage that reduces system efficiency. The retaining ring's plain mechanical function is to secure the O-ring in its groove within the hydraulic unit assembly. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HN0634-313-395. A concrete generic failure consequence is that a missing or broken retaining ring can permit the O-ring to extrude, resulting in external seepage. Keeping the retaining ring in sound condition helps maintain the O-ring's position during pressure cycles. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.006 POUNDS.
