Connectors for Liquid Nitrogen

Transfer liquids and gases into high-vacuum chambers with these assembled fittings, also known as feedthroughs. Their quick-clamp (ISO-KF) connections are easier to install and remove than bolt-on flanges.

Flanged Through-Wall Fittings
for Ultra-High-Vacuum Chambers

Bolt these fittings onto your ultra-high-vacuum chamber to transfer liquids and gases inside. Also known as feedthroughs, they come assembled with a flanged (CF) fitting, metal tubing, and two Yor-Lok tube fittings.

Precision Extreme-Pressure Stainless
Steel Threaded Pipe Fittings

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

Liquid Nitrogen Hose with Threaded Fittings

Liquid Nitrogen Hose with
Tube and Threaded Fittings

The Yor-Lok fitting is also known as an instrumentation fitting. It has two sleeves (double ferrules) that bite into metal tubing for a strong seal.

Touch-Safe Insulated Cryogenic
Hose with Threaded Fittings

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. Thread the fittings on this hose onto a freezer or other equipment in your plant or laboratory.

Touch-Safe Insulated Cryogenic
Hose with Tube Stem Fittings

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. The tube stems on each end slide into tube fittings on a freezer or other equipment in your plant or laboratory.

On/Off Valves

Threaded On/Off Valves for Cryogenic Liquids

Use these valves in cryogenic systems to control the flow of liquid nitrogen, carbon dioxide, and argon.

Socket-Connect On/Off Valves for Cryogenic Liquids

Designed to withstand extremely cold liquid gases, these valves are ideal for liquid nitrogen cooling systems and liquified gas storage. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.

Threaded Gradual On/Off
Valves for Cryogenic Liquid

Built to handle the extreme cold of liquid gases, these bronze valves are ideal for liquid carbon dioxide carbonation systems, liquid nitrogen coolant systems, and other cryogenic applications.

Solenoid On/Off Valves for Cryogenic Liquids

Built to withstand the extreme cold of liquid nitrogen and liquid oxygen, these valves are cleaned and bagged for high-purity applications.
