How it connects
The 3/8-inch quick connect is the high-pressure coupling used between a pressure washer's pump, its hose, its gun and its wand. It is not the same as the 1/4-inch plug nozzle tips and foam cannons use.
M22 is the threaded fitting many pressure washers ship with. Two diameters exist, 14 mm and 15 mm, and they are not interchangeable — this one is 14 mm, which is what the listing states.
Raincovo's listings do not name the pressure washer brands they fit — Ryobi, Sun Joe, Greenworks and the rest are not mentioned. What decides fit is the connector on your gun, wand or pump. The Raincovo Foam Cannon Parts, Bottles and Orifices guide goes through it.
