MTM M22 15mm x 3/8" QC Brass Coupler Adaptor

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

This premium adaptor has been quality tested and certified by MTM Hydro to fit a variety of pump outlets including select popular models of Sunjoe, Ryobi, AR, and Greenworks so that you can now upgrade your hose setup to Kobrajet.

MTM Hydro Stainless Steel Couplers are great for quickly disconnecting hoselines, spray guns, or any pressure washing attachments. MTM boasts a premium Stainless Steel line of fittings that ensures a worry-free cleaning experience with no concern for corrosion or unreliable performance.

All MTM Stainless Plugs are National Pipe Thread (NPT) which means they have a tapered Male or Female thread (depending upon the model). NPT is mainly used in the Western Hemisphere and was developed on the concept of interference by the third thread. When installing NPT fittings to another NPT thread we recommend that you use 4-5 wraps of Teflon tape wound clockwise or 2-3 drops of Loctite thread sealant.

British Standard Pipe Thread (BSP) is found in the European market and has a different thread pitch than NPT. BSP is also considered a 'straight thread' which means it has no taper at the end. When installing NPT on BSP or vice versa, use 6-7 wraps of Teflon or 2-3 drops of Loctite and tighten accordingly. When tightening opposing thread styles (BSP and NPT) you will experience more interference sooner and you will not be able to tighten the fitting as far as like-threads. You will still have a tight seal, just make sure to use the recommended amount of Teflon Tape or Loctite.
