How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

High-Pressure Threaded Fittings for Compressed Gas

Designed to handle high-pressure welding applications, these fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance.

Fittings with left-hand threads are identified with a notch in the nut.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.

Threaded Hose-to-Propane-Tank Adapters for Compressed Gas

Maximum Pressure: 200 psi @ 72° F
Maximum Temperature: 120° F

These adapters have a male threaded end that connects to a propane tank and a male threaded end that connects to a hose. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance. Fittings have left-hand threads that are identified with a notch in the nut.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.
