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.

For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil, Water
Tubing: Use with seamless aluminum
Specifications Met: JIC

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are aluminum, which is lightweight with good corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
