About Measuring Fittings

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

30° Flared Fittings for Steel Tubing

Specifications Met: See table

Also known as JIS (Japanese Industrial Standard) fittings, these have a 30° flare on one or both ends. Fittings are zinc-plated steel for fair corrosion resistance.

UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. They are also known as O-ring boss threads.
