Features and Benefits:
Replacing a piston pump with a diaphragm pump is simplified with the 11981 kit. Paint gun washers currently using a piston pump are easily upgraded to our powerhouse 338 pump with this kit, which also includes a solvent intake filter, two nuts, two flat washers, two lock washers, two nylon spacers, two steel tubes with flare nuts and an operating instructions decal for the washer lid.
