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.. Brass nuts have good corrosion resistance and are softer than 316 stainless steel nuts, so they're easier to thread together.. Nuts with left-hand threads are identified with a notch.
