Hastelloy C276 Tees

The Hastelloy C276 Tee is a critical piping component used to connect three pipe sections, allowing the fluid flow to be divided or combined, typically at a 90-degree angle. Manufactured and supplied by Zeron Fasteners, these tees leverage the superb qualities of the nickel-chromium-molybdenum alloy to withstand the most aggressive industrial media, including hot contaminated mineral acids, solvents, and wet chlorine gas. The material’s resistance to pitting and crevice corrosion makes these tees essential for reliable performance in chemical, petrochemical, and pollution control systems. We offer both Equal Tees (where all three outlets are the same size) and Reducing Tees (where the branch outlet is smaller than the run outlets) in accordance with ASME B16.9 specifications.
