9140 PLUNGER REPAIR KIT 25 mm P420

SKU: 3172

This is a Giant Pumps 25 mm packing kit (Giant 09140) for P420 and P420H pumps. Per Giant's repair documentation it contains three O-rings, three V-sleeves, three weep seals, and six pressure rings, the components that seal around the plungers and manage the pressure differential across the packing stack. Replace when the pump leaks at the manifold or loses pressure. Confirm the pump model against Giant's parts breakdown before ordering.
