22mm Screw Couplers for Pressure Washers

A 22mm screw coupler is the female half of the 22mm screw connection used on most European-style pressure washer guns, lances and hoses (Karcher, Kranzle, Suttner, General Pump and similar). It threads onto a 22mm screw plug and adapts that connection to standard pipe thread or a quick connect.

Pick the brand, material and the connection you need on the other end. Brass is the standard general-purpose choice; 304 stainless steel is for chemical, salt and wash-down service where brass corrodes.
