Hose Crimping Tool and Fitting Sets for Compressed Gas
Sets contain a crimping tool and a variety of fittings, nuts, and ferrules so you can connect pressure regulators, torches, and other components of your welding system. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance.
Barbed adapters let you adapt to a threaded end so you can connect welding hose to pressure regulators or torches. They consist of a barbed shaft with a rounded end that sits inside a threaded nut so you can make a threaded hose connection.
Barbed connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose. Slide the barbed end into welding hose and use a hose ferrule and the crimping tool to secure the fitting to hose.
Threaded connectors let you attach threaded welding hose to pressure regulators and torches.
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.
