These are the US standard fittings for oxy-fuel connections. Fuel is left hand thread, and the nuts have hash marks across the corners to identify them. Oxygen fittings are right-hand thread and have no marks on the nuts.

What is the threading size for oxygen outlets?
· The connecting equipment must have the proper type of threading to mate onto its corresponding valve. For oxygen service this is a CGA-540 connection. This connection consists of clockwise turning threads on a male connection. To connect to it requires clockwise threads on a female connection.
What type of thread does an oxygen cylinder regulator have?
Brass nuts have good corrosion resistance and are softer than 316 stainless steel nuts, so they're easier to thread together. 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. For technical drawings and 3-D models, click on a part number.
What are oxygen connectors made of?
What type of threads does oxygen have? Right handed threads. What type of threads does acetylene have? Left han ded threads. How to you identify the acetylene valves. marked "Fuel" or have notches in the nut. what does the regulator do and what does the regulators on the hoses do? Reduce high cylinder pressure to low, and makes the hose ...
What type of connection is used for oxygen service?
There will be different CGA connections for the same gas but at different fill pressures. There are also either RH (right-hand) or LH (left-hand) threads. LH threads are backwards or left instead of the normal right threads and this is odd, because it is …
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.
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.
High-Pressure Nipples for Compressed Gas
Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut (sold separately) so you can make a threaded connection.
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.
