Check Valve Kit (3 Pack) SprayTech
Check valve replacement kit ( 3 pack )
For SprayTech CAPspray HVLP spray guns, Wagner NBC gun, Wagner's Hvlp Conversion gun, and Maxum gun.
We recommend you keep this part on hand for the above guns. Check valves are the only part that we ever replace on our personal guns.
Some people do clean these valves out and reuse them. But most agree it is easier to replace them.
