Description

What is a grooved ring seal in pressure washers?

A grooved ring seal has a circular ring with a grooved design that helps create a tight seal between two mating surfaces or components in the pressure washer. The grooves on the ring seal aid in retaining the fluid and preventing its escape, ensuring proper containment and efficient operation of the pressure washer. 

These grooved ring seals are commonly found in pump connections, hose fittings, or spray gun connections where fluid flow needs to be tightly controlled and sealed.

Why do you replace them?

Seals can experience wear and tear due to continuous use, exposure to high pressures, temperature fluctuations, or contact with chemicals. Leaky seals result in reduced performance, loss of pressure, water wastage, or even potential damage to other components of the pressure washer. 

Is it a genuine spare part? 

This grooved ring seal by Karcher is a genuine pressure washer replacement part. Your pressure washer can work good-as-new in cleaning surfaces.

Ordered these grooved seals for my Karcher pressure washer and although they were quite expensive they did the job and got it running again. Speedy service from Ransom Spares

I believe Karcher pressure washers require 3 of these rings. Can you confirm this is sold individually, or as a pack of 3?

Hi Jeff, please submit a part enquiry including the TYP number beginning 1. from the rating plate on the bottom of the pressure washer so we can locate the grooved rings required for your model.
