5/16 STEEL CHECK BALL (Anderson SY28-112151)

A worn check ball can allow fluid to bypass, reducing system pressure and causing erratic operation. This aftermarket replacement part references the Anderson catalog and cross-references part number SY28-112151. The check ball is a small spherical component that seats in a valve or 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 will fail to seal, leading to internal leakage and loss of function. The item ships at approximately 0.005 pounds. Verify the serial number or application, then call (562) 693-7748.
