MTM Hydro Brass 14mm Plug to 15mm Plug Conversion Adapter

The MTM Hydro 14mm Plug to 15mm Plug Conversion Adapter allows you to use the MTM Hydro Female M22 Adapter and plug it right into our MTM Hydro Pro Kit or Snub Nose Kit. This adapter is most often necessary when you have a SunJoe pressure washer. If you are using this 14mm to 15mm Adapter, you will also need to purchase the MTM Hydro Female M22 Adapter!

This conversion adapter is necessary for new SunJoe pressure washers that have a slightly larger hose fitting, requiring the larger 15mm side of the adapter. The other threaded side of the adapter will work perfectly with the M22 Female Adapter, which then provides you with a quick-connect into the 3/8" Plug on our individual spray guns, Pro Kits, and Snub Nose Kits.

    I have a SunJoe electric pressure washer and with this fitting and a few others was able to adapt it to my MTM Hydro SGS28 Snub Gun. Thanks Esoteric!
