The ASC Engineered Solutions 310517206 is a 2.5-inch extra heavy black malleable iron tee designed for threaded pipe assemblies in demanding plumbing, mechanical, and industrial piping systems. Malleable iron construction provides the ductility and strength needed to handle mechanical stress without cracking, making this fitting a reliable choice for high-load or high-vibration installations. The black coating offers corrosion resistance suited to interior piping applications. At 8.42 pounds, this is a substantial fitting built for robust service. Licensed plumbers and pipefitters are the typical installers for this class of fitting.
This tee is used in extra heavy-duty threaded pipe systems where standard fittings are insufficient. Typical applications include industrial process piping, fire protection systems, and commercial mechanical rooms where elevated pressure ratings or mechanical durability are required. It is suitable for gas, steam, water, and air service in systems using 2.5-inch NPT threaded pipe. Domestically produced, it meets the expectations for quality and dimensional consistency demanded in commercial and industrial projects.
Designed as an OEM-style replacement or direct installation fitting for extra heavy-duty 2.5-inch NPT threaded malleable iron piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical codes and ASME B16.3 standards for malleable iron fittings. Depressurize and isolate the pipe system completely before cutting in or replacing any fitting. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-torque threaded connections, as this can damage the fitting or pipe threads.
