  • Suttner Screw Coupler: M22 14mm x 3/8" Female NPT - Non Swivel - Stainless

    M22 fittings are mainly used on residential and European power washers as a safe and secure way to provide a consistent method for attaching and detaching fittings. They may not be as fast as the traditional Quick Connect style fittings but tend to be less problematic.

    Rated for 7250 PSI and 300 degrees.

    When purchasing M22 fittings keep these tips in mind:

    • The black portion is considered the Coupler. The fitting with the exposed threads is considered the Plug.
    • 3/8" fitting size is typically used for connections on the power washer, hose and spray gun inlet.
    • 1/4" fitting size is typically used for the spray gun outlet and lance fittings.
