Description

The Graco 288779 Regulator Valve Parts Kit contains service components required to rebuild or repair the internal mechanism of a Graco regulator valve. A regulator valve controls the downstream fluid or air pressure to maintain consistent performance in spraying or fluid delivery systems. Using genuine parts helps preserve operational integrity and extend the life of the regulator assembly.

Frequently Asked Questions

The kit includes internal regulator components such as various seals, O-rings, springs and seats used to service a regulator valve.

No. It is a parts kit for servicing the internals of an existing regulator valve; the regulator body must already be installed on your machine.

Check your machine’s parts diagram or manual to confirm that the regulator assembly uses Graco part number 288779. If your regulator model matches one of the listed compatible assemblies, this kit will be suitable.
