Not universal to all models
In order to use this hose with pressure washers that have quick couplings you will need to buy the quick connect fittings from your local hardware store. They are not stocked by [...] Karcher. Factor this into the cost of your hose before buying.

Perfect Fit
Used my pressure washer often. Neighbors want to use it. Great for cleaning my 5th Wheel Trailers, road grime and dirt off my truck, clean & rinse the engine compartment. Have used it to strip peeling paint off my house, saving many hours of time in the painting process. Great for removing stains from sidewalks & driveway as well as dirt buildup in cracks. Would be lost without it!!!

It Works
This hose fits a Karcher power washer. It works very well to get the pressurized water from the pump to the gun. My old one didn't do that so this is better and I would recommend it.
