Pressure washer quick connects: identify the joint
A quick connect has a plug and socket that snap together. It is different from the threaded M22 joint, even when both appear elsewhere on the same hose or gun.
What to do
- Identify whether you are checking the washer outlet, hose end, or gun inlet.
- Look for the actual plug and socket that meet.
- Find the manufacturer part number and stated quick-connect size.
- Confirm pressure rating and any required adapter before connecting.
Do not use nozzle quick-connect dimensions to identify a hose fitting. The Kärcher US spray gun guide distinguishes quick-connect guns from M22 connections and describes an adapter supplied with VersaGRIP.
