MTM Hydro's Stainless Steel Plugs offer a fast and upgraded QC system for your high-pressure joints which are great for quickly disconnecting hose lines, spray guns, or any pressure washing attachments. MTM Hydro boasts a premium Stainless Steel line of fittings that ensures our customers a worry-free cleaning experience with anti-corrosive properties and ultra-reliable performance. They are commonly found at all joints where high-pressure fluid may need to be disconnected after use. Other areas such as lances, tips, and foam cannons are convenient places to install these QC's and with MTM Hydro's stringent Quality Control you will not have to worry about locking balls falling out, missing O-rings, or collars that do not fully engage.
As a rule of thumb, MTM Hydro 1/4" fittings are normally found at the end of the pressure washing system on the spray wand or outlet of the spray gun. When purchasing plugs and couplers the Male model has exposed threads while the Female version has threads on the interior of the fitting. See image for reference.
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.
