Veloci's brass 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 expedited cleaning experience. Veloci 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.

Veloci couplers 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. As a rule of thumb, Veloci’s 1/4" couplers are normally found at the end of the pressure washing system, on a spray wand or outlet of the spray gun. When purchasing plugs and couplers the male fitting has exposed threads while the female fitting has threads on the interior of the fitting. See image for reference.

All Veloci fittings are National Pipe Thread (NPT) which means they have a tapered male or female thread (depending upon the model). NPT is mainly used in North America 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, but will still have a tight seal, just make sure to use the recommended amount of Teflon tape or Loctite.
