Karcher Pressure Washer Grooved Ring9.078-015.0

How does a grooved ring work on a Karcher pressure washer?

The grooved ring helps to create a seal between the pump head and the high-pressure outlet connection. It has grooves that interlock with corresponding grooves on the pump head and outlet for a secure and leak-free connection. 

The grooved ring acts as a barrier to prevent water from escaping and maintain the high-pressure flow.

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. Your pressure washer can work good-as-new in cleaning surfaces.
