Karcher Pressure Washer Grooved Ring6.363-435.0

This is a genuine grooved ring for your pressure washer. 

Locks the high-pressure hose securely to your pressure washer’s pump head—ensuring a tight, leak-free connection for steady, powerful cleaning. It helps maintain consistent water pressure so your machine runs smoothly and efficiently.

Over time, wear from water, pressure, and detergents can weaken the ring or affect its fit. If you’re spotting leaks or a dip in performance, it’s a good idea to replace it with this part.
