The ASC ENGINEERED SOLUTIONS 310539804 is a 2.5-inch extra-heavy (XH) black malleable iron coupling designed for threaded pipe systems in commercial and industrial plumbing applications. Manufactured to ASTM A-197 specifications, this coupling features female pipe thread (FPT) connections on both ends conforming to ASME B1.20.1 thread standards. Pressure rating meets ASME B16.3 requirements. At 5.45 pounds, this is a substantial fitting built for demanding service conditions. Licensed plumbers and pipefitters working on black iron pipe systems will find this coupling appropriate for gas, water, and mechanical piping runs where XH-rated fittings are specified.
This coupling is suited for residential and commercial plumbing and mechanical systems requiring extra-heavy wall fittings. XH-rated malleable iron couplings are commonly installed in high-pressure or high-demand piping systems, including gas distribution, compressed air, fire suppression, and industrial process lines. The black finish makes it a standard choice for gas piping installations where galvanized fittings are not required or preferred.
Designed as an OEM-style replacement or new-installation fitting for 2.5-inch threaded black iron pipe systems where ASME B16.3 extra-heavy malleable iron couplings are required.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC, and IPC requirements. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape rated for the service fluid before making up threaded connections. Do not over-torque threaded connections, as malleable iron fittings can crack under excessive force.
