High-Temperature Nickel Tubing
- Temperature Range: -320° to 1200° F
- Bending Method: Tube Bender
Also known as Inconel, this tubing has the highest temperature rating of all the non-stainless steel tubing we offer. It has excellent corrosion and chemical resistance. It’s also seamless—the smooth interior won’t restrict flow. You can flare the ends without splitting the tubing, and weld to connect. All sizes meet ASTM B163, which is an international standard for tubing dimensions.

Acid-Resistant Yor-Lok Fittings for Nickel Alloy Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Hydrofluoric Acid, Mineral Oil, Salt Water, Steam, Sulfuric Acid, Water
- Temperature Range: -325° to 900° F
- Tubing: Use with seamless soft 400 nickel
- Specifications Met: See table
Made of 400 nickel, these Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. 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-tight seal. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
