Overview

Nilfisk piston oil seal kit for the NA5 pump on Nilfisk MH 4 and MH 5 series hot water pressure washers. The oil seals stop water getting past the pistons into the crankcase and turning the pump oil milky.

If the oil looks milky, remove the pump head, check the pistons for cracks or scoring, fit new oil seals from this kit and refill with the correct pump oil before reassembly.
