, 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. 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. This article describes existing standards and the standards in use for a number of countries. For disposable containers the availability per country is described. Filling stations may be able and allowed to fill foreign containers if adequate adapters are available. Adapters are provided by, amongst others, camping stores. The iOverlander database maintained by travelers, My LPG and the Facebook group "Cooking Gas Around the World" provide more information about individual sources per country. Much general information about global LPG use and standardization is available from the World LPG Association and the AEGPL

Connector types and standards

The list of standards shows one applicable standard for each connector type listed in the table below. A single applicable standard has been chosen in case multiple versions of the same standard have been published, for example a German and a European version.

Overview of standards

List of connector types

The Connector Types Table lists connectors that are found on propane, butane and LPG containers, the standards these connectors adhere to as well as the most important parameters of these connectors.
