It allows you to quickly connect a 1/2-inch outside diameter nylon or polyurethane air line to a 3/8-inch male NPTF threaded port without needing wrenches for the tubing side. You typically replace these when upgrading to PTC from compression fittings, remodeling air lines, or when a fitting develops a leak at the O-ring or thread seal.
