A soft metal frequently used with air, gasoline, natural gas, propane, and plumbing applications. Tubing is not as corrosion resistant as stainless steel.

Pair these nuts with vibration-resistant compression sleeves and fittings for a strong seal on stainless steel tubing.

This hose meets CGA (Compressed Gas Association) standards for use with oxygen and acetylene gas.

These CGA adapters have a male threaded end that connects to a propane tank and a male threaded end that connects to welding hose.

Use these CGA fittings to connect welding hose to pressure regulators and torches.

These couplings consist of a plug and socket that connect and disconnect quickly. Use them if you need to frequently link and unlink welding hoses, torches, and regulators. They are also known as CGA couplings.

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 to make a threaded connection.
