Karcher High-Pressure Hose Extension for K2, K3, K4, K5
For the Karcher K2, K3, K4, and K5 pressure washers, you need to know that they all have a proprietary connection which will limit your attachment options. But, don’t worry, I’ve done all the legwork to get you what you need in this kit.
If you’re looking to use an aftermarket sprayer like my Original Mosmatic Swiveling Sprayer with the K2-K5, you’re going to need this hose extension with this specific Karcher adapter.
Also, you will not be able to replace the OE hose. You can only extend it with a High-Pressure hose.
