MTM Hydro's Brass Quick Couplers are great for quickly disconnecting hose lines, spray guns, and many other pressure washing attachments. Items such as lances, tips, and foam cannons can be quickly transitioned  for an expedited cleaning experience. MTM brass is of the highest quality available, but even our fittings will show signs of discoloration after a few months of consistent use. For higher PSI ratings and anti-corrosion options, check out our Stainless Steel line of fittings.

MTM Hydro Couplers are offered in various sizes to accommodate the multitude of industries and attachments available. Keep in mind, though; couplers can only receive like-sized plugs; i.e., 1/4" Coupler must be paired with a 1/4" Plug.

 All MTM Brass Couplers are National Pipe Thread (NPT), meaning they have a tapered Male or Female thread (depending upon the model). NPT is mainly used in the Western Hemisphere and was developed on 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.
