Propane, butane, and LPG container valve connections

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.

This requires adequate tooling and adapters for replenishment in multiple countries.

For example for overlanders and users of autogas traveling with a container originating in one country to other parts of the world this is a major concern.

The iOverlander[2] database maintained by travelers, My LPG[3] and the Facebook group "Cooking Gas Around the World[4]" provide more information about individual sources per country.

Much general information about global LPG use and standardization is available from the World LPG Association[5] and the AEGPL[6] The main containers of liquefied petroleum gas, propane and butane are automotive tanks, disposable cylinders, permanent tanks and portable cylinders.
