Abstract
A conduit is provided for use in association with an air conditioning or refrigeration system. The conduit has first and second conduit portions, and a swivel providing fluid communication between the first and second conduit portions. The swivel permits rotational movement of the first conduit portion relative to the second conduit portion. The swivel is constrained to prevent linear movement between the first and second portions at the swivel. The conduit also has a fitting for external connection of the conduit to a pressure port of an air conditioning or refrigeration system. The conduit provides sealed fluid communication from the first conduit portion, swivel and second conduit portion to the air conditioning or refrigeration system when the fitting is connected to the air conditioning or refrigeration system. There are also conduit adapters, injection hose assemblies, charging manifolds with swivels, and methods of utilizing such conduits and swivels.
