Pressure Washer Accessories: What Fits Your Washer
Picked from manufacturer specs and manuals; we haven't tested these units.
Before buying any attachment, check three things on your washer and the accessory's listing: the accessory's max PSI rating, the connection type (such as a 1/4-inch quick connect) and the hose connection your manual lists. Some guns need an adapter.
Fit check first: PSI rating, connection type, hose connection, adapters
Connections differ: check your washer's manual and the accessory's listing for the connection type (threaded or quick-connect) and its PSI rating. Tips and many accessories use a 1/4-inch quick connect, and hoses and wands use threaded fittings. Some guns need an adapter. Each card below quotes the connection its maker states.
