It connects 5/8-inch nylon air brake tubing to a 1/2-inch male NPTF threaded port. The swivel design allows the body to rotate after installation, making it easier to align the air line without twisting. These fittings are typically replaced when upgrading air lines, repairing leaks, or during routine air system maintenance.
