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 Brass Threaded Pipe Fittings

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer. The male threads are rolled for excellent strength in extreme-pressure applications. Fittings are brass for good corrosion resistance.

Inline tees are also known as branch tees. Right-angle tees are also known as run tees.
