5/16 STEEL CHECK BALL (Hyundai HN10J10)

A worn check ball can allow fluid to bypass, reducing system pressure and causing erratic operation. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HN10J10. The check ball is a small spherical component that seats against a port to permit flow in one direction only. Its plain mechanical function is to block reverse flow when the ball is pressed against its seat by spring or pressure. A common failure consequence is that a damaged or pitted ball fails to seal, leading to internal leakage and loss of holding force. The item ships at approximately 0.005 pounds. Verify the serial number or application, then call (562) 693-7748.
