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:
- US POL
- British POL- Female Connectors:
- Shell Connector / French Connector
- Italian Connector- Clip on Connectors
POL Connectors / Male Connectors
This connection is screwed into the counter part on the gas cylinder.
| W | |
|---|---|
| US POL | 0.88” |
| British POL | 5/8” |
Female connectors
This connection is screwed onto the counter part on the gas cylinder
| Type of connector | W1 | W2 |
|---|---|---|
| Shell Connector / French Connector | 19mm | 27mm *) |
| Italian Connector | 17.5mm | 25mm |
*) Sometimes larger nuts are used
Clip-On Connector – 20mm
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 connector | North & South America, East Asia |
|---|---|
| British POL connector | United Kingdom |
| Shell or French Connector | Africa, Western Europe, Middle East |
| Italian Connector | Italy, North-East Africa |
| Clip-On Connector 20mm | Malaysia, Indonesia |
NOTE:
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.
