GRACO 557998 – Relief Valve Repair Kit for Trabon Meter-Flo Pumps, 1500 psi Maximum

GRACO 557998 is the relief valve repair kit for Trabon Meter-Flo pumps. It restores the internal pressure relief valve that protects the pump against high-pressure overload conditions. The relief valve is adjustable from 300–1500 psi and must not be used in a continuous bypass situation, which can cause premature pump failure.
