ShurFlo 94-910-05 Viton valve assembly kit for ShurFlo 5050 / 505X series diaphragm pumps (5059-1311-D011 and similar 12 V 5 GPM sprayer pumps). The valve assembly is what lets the pump prime and hold pressure. When the Viton valves swell, stick, or trap debris, the pump runs but won't prime, pulses, or bleeds pressure back when you close the gun. Swapping this assembly is a 10-minute fix. It fits both the NPSM and NPT versions.

In stock at our Spokane, WA shop. If the pump also won't shut off or won't start, add the pressure switch (94-910-02).
