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 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.
Replacement High-Pressure Hoses for Kärcher Professional Pressure Washers
Find replacement high-pressure hoses for Kärcher Professional pressure washers, with a wide range of hose lengths, pressure ratings, internal diameters and connection types available to suit different machines and trigger gun configurations.
Kärcher Professional pressure washers have used several different high-pressure hose connection systems across current and previous generations of machines. Our range includes hoses with EASY!Lock TR22, M22 and AVS connections, together with specialist configurations for pressure washers fitted with integrated or automatic high-pressure hose reels. Replacement hoses are also available for different generations of Kärcher trigger guns, including EASY!Force, EASY!Lock Classic, EasyPress and Classic systems.
Choose from genuine Kärcher Professional hoses, economical Kärcher Classic hoses and selected Kärcher K/Part alternatives. The range includes standard replacement hoses alongside specialist options such as Anti!Twist, rotatable, non-marking and food grade hoses for more specific professional cleaning applications.
High-pressure hoses are available in different DN sizes, working lengths, pressure ratings and temperature ratings. Selecting the correct specification is important, particularly on higher-flow, high-pressure and hot-water machines where the hose must be suitable for the performance of the pressure washer.
When choosing a replacement hose, check the connections at both ends of your existing hose as well as its length, DN size, pressure rating and compatibility with your pressure washer and trigger gun. Where a hose is intended for a machine fitted with a high-pressure hose reel, the reel connection should also be checked before ordering.
