About Karcher HK 4 High Pressure Hose Upgrade Kit for Post 1992 K2 Models

The Karcher HK 4 High Pressure Hose Upgrade Kit brings older Karcher washers up to date. It is made for K2 to K3 machines built between 1992 and 2010. Those used a screw thread hose connection. This kit swaps that for the Quick Connect system.

Karcher launched Quick Connect in 2010. You click the hose in. No more fiddly threads. The Quick Connector Adapter in the box does the conversion. It lets the old machine take modern Quick Connect hoses.

A replacement hose is included. It gives extra reach and clicks into place. To disconnect it you press the yellow release button. That makes it safe and easy to remove the hose when you change attachments. Storage after use is simpler too.

Why not buy a new washer? If your older K2 or K3 still works well this kit is a cheap way to keep it going. It suits tradespeople and contractors who trust a reliable machine. Check the build date of your washer before you order.

The Technology Explained

The old screw thread needs several turns to seal and can wear over time. Quick Connect uses a push-in fitting with a release button, so a joint is made in a second. The adapter bridges the machine outlet to that new fitting. The replacement hose then plugs straight into it. Your pump and motor do not change. Only the connection does.

Using It Safely

Switch the washer off and release the trigger to clear pressure before you change any hose. Check the click is fully home by giving the hose a gentle tug. Do not use a damaged hose. Keep the hose free of kinks. Only fit the kit to the K2 or K3 machines named by Karcher.
