Fluid end valve components for the GP5142 — the valve casing, suction and discharge valve assemblies, upper and lower O-rings for each, valve holder plate O-ring, valve holder pressure spring, plugs, and retaining hardware. The suction and discharge valve assemblies are sold as complete units and include their respective seals.

Valve wear typically presents as erratic pressure, difficulty priming, or a pump that won't hold rated output after a plunger repack. Three suction and three discharge valve assemblies are required per pump. If replacing both sides, the GP5142 Complete Valve Repair Kit is the more efficient option. Source individual valve assemblies or O-rings here for targeted repairs.

For plunger and seal components, see GP5142 Plunger & Seal Parts. Valve part numbers in this group are shared with the GP5132.
