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

Made to tighter tolerances than other stainless steel pipe fittings, these are also known as instrumentation fittings. The male threads are rolled for extra strength in extreme-pressure applications. Fittings are commonly used to connect equipment in gas and hydraulic fluid lines. They are 316 stainless steel for excellent corrosion resistance. UN/UNF (SAE Straight) threads are also known as O-ring boss threads; the male threads have a gasket to prevent leaks.

Extended-Life Pressure-Regulating Valves for Cryogenic Liquids

For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen
Temperature Range: -320° to 150° F

For a longer service life than standard valves for cryogenic liquids, these have a durable bronze body. All are cleaned and bagged for oxygen service and other high-purity applications. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves are designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen. They have an internal strainer to trap debris.
