  • MTM Adapter: M22 Plug 14mm x 3/8" QC Coupler - Stainless

    This adapter converts a M22 coupler into a 3/8" QC Coupler.  Typically this adapter would be used to connect a hose with M22 fittings to a spray gun with a QC plug on the inlet.

    Rated for 4000 PSI.

    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.
