About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.

Straight Adapters with Gasket

Male x Male

UN/UNF (SAE Straight) Thread—Also known as O-ring boss threads.

316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

Fluoroelastomer—These gaskets resist a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.

Long-Life Pressure-Regulating Valves for Cryogenic Liquids

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.
