Includes Husky air chuck and quick disconnect end fittings. Husky has a lifetime warranty on their tools should anything ever not work right. The Husky quick-disconnect fits both air chuck sizes, depending on which type you use for your air tools and has a push button quick-disconnect so you can stay hooked up but no air can pass. Handy so when you change a drill bit or set down a tool like a drill or rivet gun it won't accidentally run if it falls or gets bumped, or you hit the trigger. It's a great safety tool and a must for serious mechanics. There are no intials or engravings on the tools.
