Veloci's Stainless Steel Couplers 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. Stainless Steel fittings ensures 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 stringent quality control you will not have to worry about locking balls falling out, missing O-rings, or collars that do not fully engage.

All stainless couplers 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.
