How A Regulator Works

Propane tanks contain a flammable liquid that is pumped from larger tanks into the smaller ones used for the home consumer. Since this gas is a liquid under pressure that becomes a lighter-than-air substance when being consumed, it can build to a very high pressure. This pressure must be regulated as it exits the tanks, or else it can rupture hoses or, worse yet, create a substantial explosion. Pressure regulators are generally used on propane systems for this exact reason: to dispense the liquid in the tank so it can be consumed in a safe and efficient manner.

Propane Regulators and Their Connections

Propane regulators and their connections to propane tanks are made of brass. Brass is normally used because it is resistant to sparking. In other words, if you were to slip with the wrench when tightening the fitting from the regulator to the tank, a spark would not necessarily be created. Sparks and propane can lead to a deadly combination. Aluminum is another metal that is used in the construction of the regulator. Not only is the metal lightweight, but it also has a resistance to being a spark generator. Generally, the housing that holds the mechanism of the regulator is made of aluminum. Most regulators look as if they were modeled from a flying saucer. This saucer design contains the interior controlling diaphragm. At the top and center of the saucer is a round cap. This round cap contains the pressure spring.
