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.

Threaded Hose Fittings for Compressed Gas

Use these CGA fittings to connect welding hose to pressure regulators and torches.

Threaded Hose-to-Propane-Tank
Adapters for Compressed Gas

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

Threaded Hose-to-Propane-Torch
Adapters for Compressed Gas

These CGA adapters allow you to connect a hose to a propane torch.

Nuts for Barbed Hose Fittings for Compressed Gas

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.

Hose Crimping Tool and Fitting
Sets for Compressed Gas

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.

Barbed Hose Fittings for Compressed Gas

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.

Quick-Disconnect Hose Couplings for Compressed Gas

These couplings consist of a plug and socket that connect and disconnect quickly. Use them if you need to frequently link and unlink welding hoses, torches, and regulators. They are also known as CGA couplings.

Nuts for High-Pressure Nipples for Compressed Gas

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

High-Pressure Threaded Fittings for Compressed Gas

Designed to handle high-pressure welding applications, these CGA fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders.

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 to make a threaded connection.

Natural and LP Gas Hose Fittings

Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket that connect and disconnect quickly.

Dust Caps and Plugs for Natural
and LP Gas Hose Fittings

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.

Nuts for 37° Flared Fittings for Stainless Steel Tubing

37° Flared Fittings for Stainless Steel Tubing

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.
