This is a genuine grooved ring for your pressure washer.
Secures the high-pressure hose to the pump head, ensuring a tight, leak-free connection for steady water flow. It helps maintain consistent pressure so your pressure washer performs at its best—delivering powerful, efficient cleaning every time.
Over time, wear from pressure, water exposure, and cleaning chemicals can cause the ring to weaken or lose grip. If you're noticing leaks, loose connections, or reduced performance, replace it with this part.
This grooved ring for your pressure washer is from Karcher.

These are really good particularly as they are off an oldish machine. Increased pressure of pump and stopped leaks
Cured leak on my pressure washer. Bit tricky to install as the pump had to be completely dismantled after taking out of outer case.
Bought this item and it’s fit right where is suposed to work. Thanks
good details on the website so I am assured of purchasing the right part
Old ring was easy to get out, the new one fitted easily with a little gentle finger pressure. I thought over £4 for single ring is a bit steep when it is best to swap all three whilst you have the washer in pieces.
