Gas Cylinder Connections

Different gas cylinder connectors – also known as gas bottle connectors – are being used in various countries all over the world and often also in the same country.

The most common gas cylinder connectors that we encounter are:

POL Connectors / Male Connectors

This connection is screwed into the counter part on the gas cylinder.

Clip-on Connector

Gasolec provides the PR021A regulator with integrated Clip-On -20mm – connector for output gas pressures of 50-190mBar. The picture shows two of these regulators, from the side and from below. They come with a 9mm hose socket.

From experience we know:

US POL connectorNorth & South America, East Asia
British POL connectorUnited Kingdom
Shell or French ConnectorAfrica, Western Europe, Middle East
Italian ConnectorItaly, North-East Africa
Clip-On Connector 20mmMalaysia, Indonesia


Many of the smaller gas pressure regulators – up to 10kg - come with an ¼”Female inlet in which one can screw a gas cylinder connection. At Gasolec we often supply these gas pressure regulators including the gas cylinder connections. The point is that when such a gas pressure regulator is directly attached to one gas cylinder, that the maximum capacity of such a regulator drops to about 1 to 1.5kg of Propane/h which is the maximum capacity of a gas cylinder.
