Control of Liquids, Gases, and Solids

Through-Wall Fittings for High-Vacuum Chambers

Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs.

Precision Extreme-Pressure Stainless
Steel Threaded Pipe 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

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

Touch-Safe Insulated Cryogenic Hose with Tube Stem Fittings

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

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

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.
