5/16 STEEL CHECK BALL (Raymond RA550-008-21)

A worn check ball can allow fluid to bypass, reducing system pressure and causing erratic operation. The Raymond catalog reference RA550-008-21 identifies this aftermarket replacement part. This 5/16 steel check ball functions as a one-way valve, permitting flow in one direction while blocking reverse flow. A failed check ball may lead to load drift or uncommanded movement. Keeping a check ball in sound condition helps maintain consistent pressure control. Verify the serial number or application, then call (562) 693-7748. This part is a steel ball used in valve assemblies to seal against a seat.
