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.

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.

Quick-Clamp Through-Wall Fittings
for High-Vacuum Chambers

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.

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.
