MTM HYDRO quick connect fitting

1/4″ QC Attachment

These MTM Hydro Stainless Steel Quick Connect Plugs offer you an anti-corrosive Quick Connect system for your pressure washer accessories. These plugs are great for quickly disconnecting spray guns, lances, tips, foam cannons or pressure washing attachments. These connections are usually found at the end of a pressure washing system to make it a quick release system, such as the MTM PF22.2 foam cannon. These plugs fit directly into a ¼” coupler to make a quick release system.

  • ¼” Male Quick Connect plug comes pre-taped for you.
  • Corrosion resistant stainless steel.
  • National Pipe Thread (NPT) – The thread is tapered, so when installing, it is not designed to screw all the way in.

Useful Information

When purchasing plugs and couplers, the Male end has exposed threads while the Female version has threads on the interior of the fitting.

All MTM Hydro stainless steel plugs are National Pipe Thread (NPT), which means they have a tapered thread at the end, so they do not screw all the way in.

British Standard Pipe Thread (BSP) is found in the European market and has a different thread pitch than NPT. BSP is 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 tape or 2-3 drops of Loctite and tighten accordingly.
