The main types of pressure washer hose connections are M22 threaded, 3/8-inch quick connect, and 1/4-inch quick connect fittings. M22 connections are common on small residential units, while quick connect fittings allow for fast and easy attachment or removal of hoses and accessories. 3/8 is the standard for hoses going from the pressure washer to the gun, while 1/4in is the standard after the gun for tips.
