Gas Cylinder Connectors & Tube Fittings
Cylinder connectors are essential components used to connect gas handling apparatus, such as pressure regulators or pigtails, directly to high-pressure gas cylinders. These connectors enable the safe and efficient transfer of gases from the cylinder to the downstream equipment.
The actual design and configuration of the cylinder connector can vary depending on the type of gas stored in the cylinder. To ensure standardisation and safety, the Compressed Gas Association (CGA) has established a set of guidelines and codes known as CGA Connection Numbers. These codes specify the type of connector required for specific gases and help prevent accidental misconnections that could lead to hazardous situations.
There are three primary types of cylinder connectors, each identified by a specific CGA Connection Number:
