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. 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.[1] are available. Adapters are provided by amongst others camping stores. 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]

Container types

The main containers of liquefied petroleum gas, propane and butane are automotive tanks, disposable cylinders, permanent tanks and portable cylinders.

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

Name Description
ABNT NBR 8614[8] Brazilan standard for automatic valves for transportable containers of 2 kg, 5 kg and 13 kg of LPG, first published in 1997.
(Portuguese name: Válvulas automáticas para recipientes transportáveis para 2 kg, 5 kg e 13 kg de GLP.
Autogas Can refer to severel connector standards, colloquially known as for example Acme, Bayonet, Dish or Euro connectors.[3]
DIN 477-1 No. 4 A DIN standard for gas cylinder valves for test pressures up to 300 bar (4,400 psi).
EN 15202[9] A European norm for LPG equipment and accessories, specifying LPG cylinder valve connections.[10]
EN 417 European norm specification concerning non-refillable metallic cartridges for liquefied petroleum gases. The EN 417 norm specifies container construction, but does however not specify any connectors.
IS-8737[11] Indian standard for LPG connectors for use with cylinders of more than 5 liter water capacity.[12]
KHK S0126 Japanese standard for LPG container valve design and manufacturing.[13]
SAEF American standard specified by U.S. based SAE International.
SANS 10019:2011[14] South African standard for connectors.[15]
SNI 1591 : 2008[16] Indonesia: Forms, materials and components, construction requirements, quality requirements, and test methods of LPG steel tube valves.
M-thread The designation used for international ISO metric screw threads.
BSP British Standard Pipe, a type of threads originating from Britain.
UNEF A Unified Thread Standard originating from the USA, where the EF designation indicates an "Extra Fine" thread pitch.

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.

gollark: But then you can't monitor *everything*.
gollark: I mean, you can do that with fewer by just running triangulation with 4 modems on the 128 most recent channels.
gollark: Actually, if you have 2048 modems, you can monitor and accurately triangulate all signals.
gollark: It's *also* for division!
gollark: Which I think is 512, yes.
