Description

How a grooved ring works on a pressure washer

The high-pressure outlet and pump head are sealed together by the grooved ring. The grooves on it fit into slots on the pump head and outlet to create a secure, leak-free connection. 

The grooved ring maintains the high-pressure flow and prevents water from escaping.

When do you replace it?

If the grooved ring becomes damaged, worn out, or shows signs of deterioration, replace it. The constant pressure and exposure to water and chemicals cause the grooved ring to degrade, leading to leaks or decreased performance. 

Regularly inspecting and replacing the grooved ring helps maintain the pressure washer and prevents water leakage issues.

Is it a genuine spare part?

This grooved ring by Karcher is a genuine pressure washer replacement part.

Just what I needed

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.

The main pressure producing seal

Saved the day!

Fitted perfectly and easily washer now works fine with no leaks. I did have to establish it was the correct one, using the Chat line, as the dimensions are not shown in the product details, which is crucial as there are many different sizes in the Karcher pressure washers. Good price compared to other suppliers, although still a bit expensive for a small rubber seal. That said it means I don't have to buy a new Washer!
