Grooved Ring

Fix Number FIX9984415

Manufacturer Part Number 6.365-394.0

This is a grooved ring, installed on the pump piston. It is sold individually and sourced right from the original manufacturer, ensuring the proper fit for your pressure washer. The function of this part is to be a seal to prevent the oil in the reservoir and the water in the pump from contaminating each other. The groove ring is known to wear over the use of your equipment and this can cause a decrease in pressure and water leakage.

Valve (Sold Individually)

Fix Number FIX9949583

Manufacturer Part Number 4.580-330.0

This part includes one pump check valve for use with pressure washers. The pump check valve and the piston regulate the flow of water through the pump assembly. It is common for the part to wear out over time, so it should be part of your regular inspection check-list. If you use your pressure washer quite a bit, we recommend having one of these on hand in your tool box.
