Metric Connections

Black metric thread accessory 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 EASY!Force & Classic Trigger Guns for TR22 EASY!Lock High-Pressure Hoses
Explore our range of Kärcher Professional trigger guns and ServoPress Controllers for compatible TR22 EASY!Lock high-pressure hoses. This category brings together EASY!Force Advanced guns, EASY!Lock Classic guns and ServoPress Controllers, making it easier to select the appropriate gun for Kärcher Professional pressure washer systems using the TR22 EASY!Lock hose connection.
Kärcher's EASY!Lock system combines the speed of a quick-release connection with the security and durability of a threaded fitting. TR22 is the EASY!Lock connection used between compatible high-pressure hoses and trigger guns, providing a secure connection while allowing the hose to be connected and disconnected quickly when required.
For general professional pressure washing, EASY!Force Advanced trigger guns use the recoil force of the high-pressure water jet to reduce the holding force required to keep the trigger operated, helping to reduce hand fatigue during prolonged cleaning. The range also includes specialist EASY!Force Advanced guns for food-related and hygiene-sensitive environments, together with ATEX-rated versions for compatible applications in potentially explosive environments.
EASY!Lock Classic trigger guns provide a conventional trigger-operated alternative for compatible TR22 hose systems, while ServoPress Controllers are available for suitable configurations where convenient adjustment of water flow and pressure directly at the gun is required.
When selecting a replacement trigger gun or ServoPress Controller, check both the connection and individual product compatibility carefully. Products within this category are intended for compatible TR22 EASY!Lock high-pressure hoses; guns for older M22 and AVS hose connections are available separately. Specialist food-related and ATEX-rated products should also be selected according to the requirements of the intended application.
