Veloci 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. 

As a rule of thumb, 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 the image for reference.

All 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 the Loctite thread sealant.
