ABSTRACT:
A coupling is provided between a hose and a fitting, such as can be used to connect to an air conditioning system. The coupling has a stem with a channel extending between first and second ends. The first end of the stem is provided with a nut for securing to the fitting, which fitting can be on the air conditioning system or on a service unit. The second end has a socket for receiving a ball and end of a nipple. The nipple is secured to the hose. The ball and socket arrangement allows the nipple and the hose to rotate 360 degrees around a longitudinal axis of the stem, as well as pivot with respect to the stem.
