For example, pressure regulators are used in gas grills to regulate propane, in home heating furnaces to regulate natural gases, in medical and dental equipment to regulate oxygen and anesthesia gases, in pneumatic automation systems to regulate compressed air, in engines to regulate fuel and in fuel cells to regulate hydrogen.

The regulator not only acts as a control regarding the flow and distribution of propane but also as a safety barrier between the high pressure of the tank and the end use appliance(s). Most will rightfully argue that the LP Gas regulator is the heart of any propane gas system.
