"Coupling is a type of connector used in plumbing and hydraulics. Couplings are made up of two parts, one called the male part and another called the female part. The female part has a stem that fits into the male part, while the male part has a nut that secures it to its mating hole. The most common coupling types are simple union couplings, threaded adapters, butt joints, pipe flanges, and pipe collars. They are used to join two pipes together when working with water supply or drainage systems.
