It connects a 3/8-inch outside diameter plastic air line (push-to-connect) to a 1/4-inch male NPT threaded port. The swivel design allows the fitting to be aimed in any direction during installation, preventing hose kinks and making it easier to route lines in tight spaces. These fittings are commonly replaced when an air leak develops at the connection point, when upgrading or repairing air system plumbing, or when a damaged fitting is found during preventive maintenance inspections.
