Kärcher bayonet and quick connect: Kärcher-only fittings
Kärcher's own hose quick connect and wand bayonet on its K-series guns: how they differ from M22, which kits Kärcher lists, and its reel and other-brand exclusions.
Also listed as Karcher bayonet, Kärcher quick connect, Karcher quick connect
Short answer
Kärcher's bayonet gun kit uses a Kärcher-specific quick connect for the high-pressure hose and a Kärcher bayonet for spray wands; neither is M22 or a 1/4 in quick-connect, and Kärcher states no dimensions. Kärcher says its bayonet guns are not compatible with other brands, and its bayonet gun-and-hose kit does not fit Kärcher models with hose reels. Kärcher's VersaGRIP gun has a Quick Connect inlet and ships with an M22 adapter for M22 machines.
Key facts
- How to recognize it

- Where makers use it
- Kärcher K-series electric washers on its finders: the spray-gun finder lists the 2.644-343.0 kit for K2-K5 electrics without hose reels; the 2.643-910.0 kit page also lists the K 1 and the K 2 Follow Me Cordless. MJJC sells a Kärcher K version of its PRO V3.0 foam cannon[2][1][3]Check your exact model on Kärcher's list.
- Adapters makers sell
- Kärcher's VersaGRIP gun (8.755-203.0) has a Quick Connect inlet and ships with an M22 adapter, needed only on machines with M22 hose connections[2]Package contents can change; check the current listing.
- Ratings on parts
- Kit 2.643-910.0: 2,000 PSI maximum. VersaGRIP and Standard M22 guns: listed for washers rated up to 4,000 PSI[1][2]
- Common mix-ups
- Kärcher's Standard M22 Spray Gun (8.641-024.0) has male M22 connections, not a bayonet. Kärcher labels 2.643-910.0 three ways on its US pages, and its spray-gun finder lists 2.644-343.0 for the bayonet kit[2][1][4]Do not treat the two kit numbers as interchangeable.
- Not confirmed
- Not confirmedBayonet and quick-connect dimensions; the kit's hose length; whether the K 5 Premium Smart Control takes the kit (it is not in the kit's chart).

- Kärcher lists its consumer trigger guns for cold-water washers only.
