These valves are common on petroleum tanker trucks, where they control the loading and unloading of fuel from the bottom. The O-ring seals the valve nose to the API adapter, preventing fuel leaks during transfer. Replace it when you notice seepage or as part of preventive maintenance to keep the coupling tight and safe.
