E-Z Clip refrigerant and hose fitting program is the way to go! Now you can complete the entire line fabrication, routing and crimping in your own garage. The unique E-Z Clip fittings are easy to make up, and the smaller diameter hose allows for tighter turns and neater routing than before. Each fitting connection is made with the proper fitting, one cage, and two cage clips. Simply slip two clips over the hose end, insert the fitting, and press the cage over the hose and into the recessed groove on the fitting. Then move the cage clips over the cage and close the clips with pliers, it's that easy! Fittings are sold individually and do not include cages or cage clips.
