Couplings are plastic, which is lighter in weight than metal 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.

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line.

Made of stainless steel, these hose fittings are more durable than plastic barbed hose fittings and have excellent corrosion and chemical resistance. Slide the barbed end into hose and secure with a clamp.

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.

Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated.

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.

Commonly used in low-pressure welding applications, these fittings connect downstream of your pressure regulator. Slide the barbed end into hose and secure with a crimp-on hose ferrule.

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.

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.
