Graco 287798 Stem Drain Valve is an OEM internal stem used in the drain valve assembly to control fluid release and pressure relief in hydraulic airless sprayers.
The Graco 287798 Stem Drain Valve is a genuine OEM internal stem used inside the drain valve assembly of Graco hydraulic airless paint sprayers. This precision-machined component controls the opening and closing of the drain passage, allowing safe pressure relief, flushing, and fluid drainage during maintenance and cleaning.
This stem is installed inside the drain valve body and is not a complete valve assembly. It restores proper sealing and smooth operation when the original stem becomes worn, damaged, or begins to leak.
