Supplied by OmniSwivel International, this very high quality swivel screws in-line between the hose and the first stage regulator body and splits one low pressure port to double low pressure ports. It allows swivel movement of one of the hoses at the first stage, the other port is a fixed position pass through, and can be used to streamline the area of the first stage by providing tighter hose routing. The low pressure version has 3/8-inch M-F fittings, chromed solid brass construction and is Nitrox Ready.
