About Pipe and Fittings

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

Ultra-Corrosion-Resistant Yor-Lok Fittings for Nickel Alloy Tubing

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.

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.
