Pressure Washer Parts

Male Adapter

$4.99

Fix Number: FIX10020893
Manufacturer Part Number: 9.134-019.0

This is a genuine male adaptor, sold individually. This male adaptor attaches to the female hose connector on your pressure washer. This black plastic adaptor is located inside the hose connector and fastens it to the pump, allowing the connector to rotate. As you use your pressure washer, the adaptor can begin to wear and can eventually break. This is a quick and easy repair, that begins by removing the inlet filter from the hose connector, then use a hex socket to remove the male adaptor and the O-ring. Install the O-ring onto the male adaptor and connect the male adaptor into the female connector. This assembly can now be installed onto the pump, and the inlet filter can be re-installed.

Grooved Ring

$6.19

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)

$9.28

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.
