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.
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.
