Upgrade older Karcher K Series pressure washers from screw-fit to modern Quick Connect convenience.
The Karcher HK 4 Gun & Hose Conversion Set provides a simple way to update older Karcher K2 & K3 pressure washers that were originally supplied with a screw-thread high-pressure hose connection. The Karcher HK4 Gun & Hose Conversion Set replaces the original screw-fit gun and hose with a modern Quick Connect trigger gun and hose combination, making setup faster and everyday use more convenient.
This conversion kit is designed for earlier Karcher K2 & K3 pressure washers that were produced before the widespread introduction of the Karcher Quick Connect system (generally around the 2008–2010 period) and still use a traditional screw-thread hose connection at the machine. If your pressure washer uses a screw-on high-pressure hose rather than a push-fit Quick Connect coupling, the Karcher HK 4 Gun & Hose Conversion Set is intended to provide a compatible upgrade path.
Once fitted, the Karcher HK4 Gun & Hose Conversion Set allows the high-pressure hose to be quickly attached and released using the Quick Connect interface, reducing effort, improving hose handling and making storage easier. It is an ideal solution for refreshing ageing hoses and trigger guns while bringing older machines closer to the convenience of current K Series models without replacing the entire pressure washer.
