Barbed Hose Fittings for Compressed Gas
Commonly used in low-pressure welding applications, these fittings connect downstream of your tank and pressure regulator. Slide the barbed end into rubber hose and secure with a crimp-on hose ferrule. Fittings are brass for good corrosion resistance.
Adapters let you adapt to a threaded end so you can connect welding hose to torches or pressure regulators. They consist of a barbed shaft with a rounded end that sits inside a threaded CGA nut (sold separately) so you can make a threaded hose connection.
