Metric Connections

Conventional threaded connections used on many older Kärcher Professional pressure washers and selected Classic Range machines. M18 connections are commonly used for nozzles and accessories, while M22 connections are used for high-pressure hoses, trigger guns and spray lances.
AVS Connections

AVS Swivel Connections
AVS connections can be used with EASY!Lock high-pressure hoses, older M22 thread trigger guns and high-pressure hose reel connections. The rotating AVS connection helps prevent the high-pressure hose from twisting and tangling during use.
Quick Connect Connections

Quick Connect Connections
Kärcher Quick Connect connections use a push-in hose fitting that is typically secured in place by a retaining clip rather than a threaded connection. Used on selected Kärcher Professional Classic hose reel machines for quick and straightforward hose reel hose connection.
Professional EasyPress, Classic & ServoPress Guns with M22 Threaded Connections
Explore our range of Kärcher Professional trigger guns and ServoPress Controllers designed for compatible M22 connections. This category brings together EasyPress M22 trigger guns, Classic M22 guns and M22 ServoPress Controllers, providing replacement options for Kärcher Professional pressure washer systems using conventional M22 threaded connections.
M22 is a conventional threaded connection used across earlier generations of Kärcher Professional high-pressure cleaning equipment. The threaded fitting provides a secure and reliable connection and remains in use on many existing Kärcher Professional pressure washers and high-pressure cleaning systems.
The range includes EasyPress M22 guns for compatible machines using Kärcher's EasyPress trigger system, together with Classic M22 guns providing a straightforward conventional trigger-operated solution. Compatible M22 ServoPress Controllers are also available for suitable pressure washers, allowing water flow and pressure to be adjusted conveniently at the gun to suit different cleaning tasks and surfaces.
When replacing a Kärcher Professional trigger gun or ServoPress Controller, it is important to identify both the gun type and connection required by the existing pressure washer system. Products within this category are intended for compatible M22 connections; guns and controllers for AVS or TR22 EASY!Lock connections are available separately. Check the individual product specification and compatibility information before ordering to ensure the correct replacement is selected.
