SCREW - BLEEDER (Hyundai HN3BC-4663)

A bleeder screw that is not sealing can allow air or fluid to bypass its intended path. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference part number HN3BC-4663. The screw functions as a threaded fastener that, when tightened, closes a passage to prevent leakage. A common failure consequence is a gradual loss of system pressure, leading to inconsistent operation. During a routine service check, a bleeder screw may show signs of corrosion or stripped threads. Verify the serial number or application, then call (562) 693-7748. The part is listed under the category Hardware Screw.
