Graco 18H056 Needle valve kit for Ultra QuickShot

*IMPORTANT* Please follow the included instructions as this part requires calibration to install correctly. If you are not comfortable doing so, please consider 18H059 - QuickShot Replacement Gun instead. If you're replacing this for the first time, the rear portion of your valve may have a pin jutting out but that has been changed and these valves are a direct replacement.
