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.

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.

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.

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

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

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.

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.

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 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.

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.

with Female Threaded Fittings

Argon, Nitrogen, and Oxygen Hose with
Male and Female Threaded Fittings

High-Temperature Argon, Nitrogen, and Oxygen Hose

Transfer industrial gases in temperatures up to 1500° F with this hose.

LP Gas Hose with Female Threaded Fittings

Change the fuel source for your propane torch from a fuel cylinder to a propane tank. This hose is often used for extended-use applications, or when a propane tank can’t be moved.
