Grooved Ring

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.
