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.

Through-Wall Fittings for High-Vacuum Chambers

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

Flow-Control Orifices for Chemicals

Made of PVC, these orifices have excellent resistance to a wide range of corrosive chemicals.

Compact Threaded On/Off Valves for Chemicals

For chemical-processing applications in confined areas, these valves have a low-profile handle to fit in tight spots. A rubber seal and a plastic body stand up to aggressive, corrosive solutions.

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.

Pipeline Fluid Blockers

Also known as pipe blinds, these fluid blockers fit between two flanges to stop flow, so you can work downstream without draining the system.
