If you want to extend your existing Karcher hose and use a hose like a High-Pressure hose you'll need to use this adapter. As of now we cannot source a solution for connecting an aftermarket hose directly to your Karcher pressure washer (K2, K3, K4 & K5) so this is the only option. This adapter comes with a stainless female 3/8 plug.One end connects to your existing Karcher hose & the other connects to an aftermarket hose with a 3/8 coupler.
