The Easy Dial Oxygen Regulator is a valve to help regulate the flow of oxygen passing through a high-pressure point. The easy grip turning handle helps you adjust accordingly, making a secure connection with the outlet of the tank. If hissing sound is made once you open the valve, re-close the valve immediately and reconnect the regulator; checking the metal ring is in place to connect with the air tank. The marked flow meter allows you to properly measure the Liters Per Minute oxygen is flowing through it
