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

Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.

Sets contain a crimping tool and a variety of CGA fittings, nuts, and ferrules so you can connect pressure regulators, torches, and other components of your welding system.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

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.

Each of these metal fittings is double bagged to prevent contamination in areas that require a high level of cleanliness.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. Also known as dry disconnects and double shut-off couplings, they have a shut-off valve in the plug and the socket for minimal fluid loss when disconnecting your hose line.

Connect your hose to a cam-and-groove vapor recovery valve.

Also known as dry disconnects and double shut-off couplings, these couplings make connecting and disconnecting your line quick and virtually spill-free. Built to stand up to petroleum products, such as diesel fuel and gasoline, their body and gasket are made from materials that won’t corrode from oil.

Built with ball bearings, these fittings continuously swivel 360° before and after installation to prevent your hose from twisting, kinking, and failing. They’re made of 316 stainless steel, so they won’t corrode from a wide variety of chemicals, as well as fuels, gasoline, and oil.

To keep contaminants out of your gas line, add these dust caps and plugs to natural and LP gas couplings when they’re not connected. All work with couplings that are rated ANSI Z21.41/CSA 6.9 for use with gas fuel appliances.

Run natural and LP gas through this heavy duty hose that's flexible enough for routing through walls and ceilings.
