Crimp-On Ferrules for Welding Hose
Use ferrules to create a permanent connection between your welding hose and barbed hose fittings. You will need a hose crimper (sold separately) for installation. Ferrules are brass for good corrosion resistance.

Metal Garden Hose Fittings
Connect these fittings to rubber or plastic garden hose for a variety of water supply applications.
Brass fittings have good corrosion resistance and are softer than other metal fittings, so they’re easier to thread together. 303 Stainless steel fittings have very good corrosion resistance, so they’re the best choice for high-humidity environments.

Metal Garden Hose Fittings for Drinking Water
These fittings meet NSF/ANSI Standard 61 for drinking water. Connect them to rubber or plastic garden hose for a variety of water supply applications. Fittings are brass for good corrosion resistance.

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

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.
316 stainless steel nipples have excellent corrosion resistance.

Threaded Hose Fittings for Compressed Gas
Use these fittings to connect welding hose to pressure regulators and torches. They are also known as CGA (Compressed Gas Association) fittings. Fittings 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.
