The Compressed Gas Association (CGA) has selected and standardized the valve outlet to be used on each gas cylinder. These standards, contained in the document “CGA STANDARD V-1, Compressed Gas Cylinder Valve Outlet Connections" , have been
CGA Fitting Reference - CONCOA
A CGA fitting is the standardized system for the attachment of a compressed gas cylinder to the required regulator or transfer line. Examples of CGA fittings would be CGA-580 for Non-flamable, Non-oxidizing gases such as Nitrogen, Argon, or Helium.

The following charts are posted to assist in matching CGA valves and fittings with their corresponding gases. This is a reference tool only. Please consult a qualified gas supplier or the CGA to determine the actual valve types and CGA connections required for your application.
What CGA connections are recommended for different gases
CGA Connections are the standardized system for attaching industrial gas cylinders to a regulator, manifold or transfer line.

The “Do’s and Don’ts” of CGA Cylinder Connections
Most people think huge amounts of force are required to get a positive seal, but look at the chart below for the CGA recommendations for torque by connection number. Not only do the cylinder labels tell us about the gas, but also CGA numbers and whether it is a LH or RH connection.
