616721 is a 3-inch, four-bolt flange tee (T-fitting) designed for ASME B16.5 Class 150 piping, delivering a 90-degree branch with bolted flange ends. It connects three pipe sections in industrial systems, commonly used in process piping, chemical systems, water treatment plants, and generic industrial fluid networks where reliable sealing and pressure containment are required. Material options include carbon steel or ductile iron, depending on the specific application, with the tee configuration optimized for bolted flange assembly in process lines and petrochemical facilities.
