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
Tubing: Use with seamless steel
Specifications Met: See table

These fittings include a nut with two sleeves (ferrules) for extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. Fittings are zinc-plated steel for fair corrosion resistance. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
