Graco 238-562 25 pk 205-264 Piston Check Valve Repair Kit Pump Replacement Part

Graco part number 238-562 is a piston check valve assembly used as a replacement component in Graco fluid transfer and spray pump systems. Each unit consists of a steel cylindrical piston body with a machined shank, topped by a molded polymer flange/cap featuring a multi-port (6-hole) orifice pattern visible on the face — a design characteristic of Graco's ball-seat or poppet-style inlet/outlet check valves used to maintain one-directional fluid flow within reciprocating pump assemblies. The parts are supplied new in OEM-style kraft box packaging with the Graco part label 238-562, and the quantity in the photo appears to be approximately 20–25 pieces, consistent with a bulk or contractor pack. These check valves are commonly installed in Graco airless paint sprayer and fluid transfer pumps such as the President, Monark, and Bulldog series, where maintaining proper seating and check function is critical for consistent output pressure and flow rate. Replacement is recommended whenever pump output pressure drops, the pump fails to prime, or fluid bypasses on stroke.
