POL is the common name for the standard CGA 510 (US Compressed Gas Association connection number). The Thread specification is .885" – 14 NGO – LH – INT, meaning 0.885 in (22.5 mm) diameter thread, 14 threads per inch (1.814 mm pitch), National Gas Outlet form, left-hand internal thread. [3]
carbon dioxide in the form of a soft drink; sulfur trioxide in the form of fuming sulfuric acid; nitrogen dioxide in the form of red-fuming nitric acid; hydrogen chloride in the form of muriatic acid. Note: these four are most often found in containers other than metal bottles, and at low pressure, e.g. 3 to 7 standard atmospheres (300 to 710 ...
Several types of valve connections for propane, butane, and LPG containers exist for transport and storage, sometimes with overlapping usage and applications, and there are major differences in usage between different countries. Even within a single country more than one type can be in use for a specific application.
However, in many European countries, this tax break is often compensated by a much higher annual tax on cars using LPG than on cars using petrol or fuel-oil.

A propane tank car after a fire, the HAZMAT 1075 symbol can be seen in red as a warning of the danger posed by the gas. A gas is a substance which (a) at 50 °C (122 °F) has a vapor pressure greater than 300 kPa (43.51 PSI) or (b) is completely gaseous at 20 °C (68 °F) at a standard pressure of 101.3 kPa (14.69 PSI).
