Frequently Asked Questions

It serves as the actuator for the prime/spray valve handle on compatible Graco airless sprayers, allowing smooth transition between priming and spraying modes.

No — this is just the knob. For full replacement of the prime/spray valve, you may need the valve body and internal parts specific to your sprayer.

Remove the old knob from the prime/spray valve handle and press the new knob onto the valve shaft until secure. Always depressurize the system before working on parts.
