More About Double Male Adapters

A pipe/hose fitting adapter is used to connect straight pipe or hose sections, to adapt to different sizes or shapes, and for other purposes. 

Pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe & hose fittings. It is a connector or a coupling threaded on both ends. Pipe nipples are used to allow items with different threads to be connected together. They are used to fit straight / tapered end hose or pipes. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam. 

A coupling (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with a socket at one or both ends that allows two pipes or tubes to be joined, welded (steel), brazed or soldered (copper, brass etc.) together.

Alternatively if a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female.

If the two ends of a coupling are different (e.g. one NST/NH threaded and one NPT threaded), then it is usually referred to as an adapter.
