Compatibility
The Karcher Quick Connect Adapter enables the attachment of the new quick fitting Karcher domestic high pressure hoses onto the older style screw thread machines.
In order to confirm this part will fit your pressure washer, type your machine's model number in the 'check compatibility' box at the bottom of the page.
How To Use
Simply screw this union onto the end of your machine's M22 x 1.5 outlet pipe fitting to enable quick release high pressure hoses to be connected with ease (see image below).

To disconnect the High Pressure Hose after connection simply push the collar in the direction of the arrows on the fitting and pull out your High Pressure Hose.
Please Note: You MUST use copper grease when screwing a metal-threaded item onto this fitting, especially when using it with the high-pressure outlet elbow. This will help prevent thread damage, seizing, or difficulty during future removal.
