32-inch high-pressure (HP) rubber scuba hose is the industry standard length for a primary Submersible Pressure Gauge (SPG), providing enough slack to route neatly under a diver's left arm and clip to a chest D-ring. These durable, double-braided rubber hoses are built to handle a maximum working pressure of 5,000 PSI (345 bar) and feature standard 7/16-inch UNF fittings for universal first-stage and gauge compatibility
