Copper Tubing with Coated Exterior for Natural and LP Gas
- Temperature Range: -90° to 210° F
- Bending Method: Tube Bender
- Compatible Tube Fittings: Flared
Copper offers good corrosion resistance, and the polyethylene coating provides an additional protective layer. Tubing has markings to identify it as a gas line. It is seamless, which provides a smooth interior for unrestricted flow. It can be flared without splitting. The tube OD dimension does not include the coating; you must remove the coating to attach fittings.

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.
Connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.

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.

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.

Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket (sold separately or in a set) that connect and disconnect quickly. All of the natural and LP gas plugs are compatible with any of the natural and LP gas sockets of the same coupling size, regardless of the pipe size. Plugs and sockets are brass for good corrosion resistance. These couplings are rated ANSI Z21.41/CSA 6.9 for use with gas fuel appliances. CSA-US and CSA Certified, they also meet U.S. and Canadian safety standards.
Plugs are also known as nipples. They have a heat-sensitive fuse that will stop gas flow in the event of a fire.
Sockets have a shut-off valve that stops the flow when the coupling is separated, so gas won’t leak from the line. They are sleeve-lock style. To connect, slide back the sleeve on the socket, insert the plug, and release the sleeve. To disconnect, slide back the sleeve and pull out the plug.
NPTF (Dryseal) threads are compatible with NPT threads.
When couplings are not connected, add dust caps and plugs to keep contaminants out of your gas line.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
Warning: Stop the flow before you disconnect the line.

Minimal-Spill Push-and-Turn Hose Couplings for Natural and LP Gas
Often used for loading and unloading gas tankers, these couplings are tough enough to handle frequent connections and designed to be virtually spill-free. The socket has a rubber lip and large handles that protect it if it’s dropped. To connect, simply push the plug into the socket and twist 90°. Also known as dry disconnects and double-shut off couplings, both the plug and the socket have a shut-off valve that holds your line when they’re separated. A close fit between the plug and socket means there's little room for gas to leak when you disconnect them. This further reduces the risk of leaks and burns from contact with extremely cold gases such as liquified petroleum (LP). The socket swivels, so you won’t have to twist your hose to attach the plug. Made of stainless steel, these couplings resist corrosion from harsh chemicals and salt water.
A complete coupling consists of a plug and a socket (both sold separately).
