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.

Female x male 90° elbow adapters are also known as street elbows.

Miniature Medium-Pressure Stainless Steel Threaded Pipe Fittings

When space is at a premium choose these compact fittings. Though small in size, they have the strength to handle medium-pressure applications. Fittings are stainless steel for very good corrosion resistance.

Female x male 90° elbow adapters are also known as street elbows.

Metric, BSPP, and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. Made from fluoroelastomer, these gaskets resist chemicals, including benzene, butyl alcohol, and ethylene glycol. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.
