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: Acetic Acid, Air, Bleach, Cutting Oil, Diesel Fuel, Formic Acid, Fuel Oil, Gasoline, Hydraulic Fluid, Iron Chlorides, Mineral Oil, Salt Water, Steam, Water
Temperature Range: 0° to 1000° F
Tubing: Use with seamless soft C276 nickel
Specifications Met: ASME B31.3

With the best corrosion resistance of any metal tube fittings we offer, these C276 nickel Hastelloy fittings stand up to aggressive chemicals and resist pitting and cracking from stress. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They include a nut with two sleeves (ferrules). The sleeves bite into tubing as you tighten the nut, creating a strong, leak-resistant seal. Fittings are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
