What must a nitrogen tank always be equipped with?

A nitrogen tank must always be equipped with a regulator to safely manage the pressure of the gas being released. Nitrogen is typically stored at high pressures, and without a regulator, the gas could be released too quickly, posing a safety hazard. The regulator ensures that the pressure is reduced to a safe and usable level, preventing sudden bursts of gas that could lead to accidents or equipment damage.

While safety valves, pressure gauges, and filler nozzles are important components in various contexts, the presence of a regulator is essential for safely controlling the flow and pressure of nitrogen from the tank during use. A regulator allows users to adjust the pressure according to the specific requirements of their application, providing better control and safety.
