To maintain the temperature of liquids as cold as -325° F, this hose has vacuum insulation and a reflective barrier. This prevents heat transfer in the same way a thermos does, so the exterior of the hose won’t freeze or form condensation. Even when used with liquid argon, liquid carbon dioxide, liquid methane, and liquid nitrogen, this hose is safe to handle.

This hose comes ready to use—you don’t need to create the vacuum yourself. To install, thread the fittings on this hose onto a freezer or other equipment in your plant or laboratory. Both ends swivel until tightened, so you don’t need to rotate the entire hose during installation. With ribbed insulation inside and spiral reinforcement outside, this hose won’t crack or leak when you bend and flex it around obstacles. The cover is 304 stainless steel, which stands up to wear and tear and won’t corrode from mild chemicals and water.

Sealed vacuum insulation and a reflective barrier inside this hose maintains the temperature of liquids as cold as -325° F. Similar to a thermos, this prevents heat transfer, so the exterior of the hose won’t freeze or form condensation. This hose is safe to handle, even when used with liquid nitrogen, liquid argon, liquid carbon dioxide, and liquid methane.

The tube stems on each end slide into tube fittings on a freezer or other equipment in your plant or laboratory. With ribbed insulation inside and spiral reinforcement outside, this hose won’t crack or leak when you bend and flex it around obstacles. The cover is 304 stainless steel, which stands up to wear and tear and won’t corrode from mild chemicals and water.

Use these fittings to connect welding hose to pressure regulators and torches. They are also known as CGA (Compressed Gas Association) fittings. Fittings are brass for good corrosion resistance.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.

Also known as CGA (Compressed Gas Association) nuts, these are designed for low-pressure welding applications downstream of your tank and pressure regulator. Slide a barbed hose adapter for compressed gas into a male or female nut to make a threaded connection to torches or pressure regulators. These nuts have good corrosion resistance.

Nuts with left-hand threads are identified with a notch.

Note: Nuts have a CGA number that corresponds to a specific type of gas. Choose a nut with the same CGA number as your tank and other system components.

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.

Slide a high-pressure hose nipple for compressed gas into one of these nuts to connect a pipe to the inlet of a pressure regulator. They are also known as CGA (Compressed Gas Association) nuts and inlet nuts.

Brass nuts have good corrosion resistance and are softer than 316 stainless steel nuts, so they're easier to thread together. Aluminum-plated brass nuts have better corrosion and wear resistance than unplated brass. Chrome-plated brass nuts have comparable corrosion and wear resistance to aluminum-plated brass nuts, and have a bright, shiny appearance. 316 stainless steel nuts have excellent corrosion resistance.

Nuts with a plastic grip can be tightened by hand instead of with a wrench.

Nuts with left-hand threads are identified with a notch.

Note: Nuts have a CGA, BS, or DIN number that corresponds to a specific type of gas. Choose a nut with the same number as your tank and other system components.

Designed to handle high-pressure welding applications, these fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance.

Fittings with left-hand threads are identified with a notch in the nut.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.
