MTM HYDRO - Stainless steel male coupler
MTM Hydro's stainless steel couplers provide a quick and improved quality control system for your high pressure joints, ideal for quickly disconnecting hose lines, spray guns or any pressure washing accessory. MTM Hydro has a range of premium quality stainless steel fittings that ensure our customers have a worry-free cleaning experience with anti-corrosion properties and ultra-reliable performance. They are usually found at all joints where high pressure fluid may need to be disconnected after use. Other areas such as spears, spikes and foam cannons are convenient places to install these QCs and with MTM Hydro's stringent quality control, you won't have to worry about falling logs, missing o-rings or clamps that do not fully engage.
Typically, MTM Hydro fittings are normally found at the end of the pressure washing system on the spray wand or spray gun outlet. When purchasing plugs and couplers, the male model has exposed threads while the female version has threads inside the fitting. See image for reference.
All MTM stainless steel couplers are National Thread (NPT), which means they have either a male or female taper thread (depending on the model). NPT is primarily used in the Western Hemisphere and was developed on the concept of third wire interference. When installing NPT fittings on another NPT thread, we recommend using 4-5 strips 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' meaning it has no taper at the end. When installing NPT over 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 encounter more interference sooner and you will not be able to tighten the fitting as far as similar threads. You will always have a tight seal, just be sure to use the recommended amount of Teflon tape or Loctite.
