About Pipe and Fittings
Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Nuts for High-Pressure Nipples for Compressed Gas
Slide a high-pressure hose nipple for compressed gas into one of these nuts to connect a pipe to the inlet of a pressure regulator. They are also known as CGA (Compressed Gas Association) nuts and inlet nuts.
316 stainless steel nuts have excellent corrosion resistance.
Note: Nuts have a CGA, BS, or DIN number that corresponds to a specific type of gas. Choose a nut with the same number as your tank and other system components.
