3/8″ QC Brass Coupler x M22 M 15mm Socket

The all-new 15mm Twist adapter offers you a consolidated option to adapt to proprietary M22 fittings that, previously kept you from upgrading the stock guns provided by the manufacturer. Standard pressure washers will have a 14mm stem required, however, in the image provided you can see the enlarged stem receiver. Some manufacturers have changed to 15mm to prevent you from upgrading through the use of aftermarket accessories, until now!

This premium adapter has been quality tested and certified by MTM Hydro to fit a variety of hose outlets including select popular models of Sunjoe, Ryobi, AR, and Greenworks so that you can, now, upgrade your guns and lance setups to MTM Hydro’s Italian SG series. Keep in mind, you could also upgrade your entire setup to Kobrajet hose with the use of the 24.5005 fittings for these same residential pressure washers.
