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.

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.

Brass nipples have good corrosion resistance and are softer than 316 stainless steel nipples, so they're easier to thread together. Chrome-plated brass nipples have better corrosion and wear resistance than unplated brass nipples and have a bright, shiny appearance.

Nipples that tighten by hand should be paired with a nut with a plastic grip.

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.

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.

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. Adapters with a spiral barbed end twist into hose for an easier installation than adapters with a standard barb.

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.

Quick-Disconnect Hose Couplings for Compressed Gas

Use these couplings to quickly link and unlink welding hoses, torches, and pressure regulators. They consist of a plug and socket that are sold together as a set of two—you’ll get one right-hand connection for oxygen and one left-hand connection for fuel gas. The connections are noninterchangeable and color coded so you can’t mix lines. The male threaded ends attach to threaded welding hose, and the female threaded ends attach to a torch or pressure regulator. To connect couplings, push the plug into the socket; the sleeve on the socket has a spring-loaded lock for gas-tight connections. To disconnect, pull back on the socket sleeve and twist to release the plug. The sockets have a shut-off valve that stops the flow when the coupling is separated so gas won’t leak from the line. The sockets also have a built-in check valve to prevent gas backflow. Couplings are also known as CGA (Compressed Gas Association) couplings. They are brass for good corrosion resistance.

Couplings with left-hand threads are identified with a notch in the nut.

Note: Couplings have a CGA number that corresponds to a specific type of gas. Make sure the CGA number of the coupling matches the CGA number of your tank and other system components.
