A POL valve (originally for Prest-O-Lite) is a gas connection fitting used on LPG cylinders.

The oldest standard for such connections, it is still the most common such fitting in some countries such as Australia[1]. POL valves are legal and quite common in the United States, especially on larger containers, although certain uses (smaller portable containers) require a modified version of the POL valve that includes some safety features.

It was developed by the Prest-O-Lite company, hence the name, and uses a left-handed thread.[1]
