MTM Adapter: M22 plug 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.
