The tested design allows users to connect and disconnect quick and easy without the need of any other tools. Applications include multiple potable liquids such as reverse osmosis drinking water, beverage dispensing, coffee machines, RV and Marine, misting systems, ice makers and many more. A quick connect fitting is a coupling used to provide a fast, make-or-break connection of fluid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections, which require wrenches.
