The ASC Engineered Solutions 810081612 is a 3-inch black malleable iron coupling designed for threaded pipe connections in plumbing, mechanical, and industrial piping systems. Malleable iron provides the strength and ductility needed to handle the stresses of installation and system pressure cycles. The black coating is standard for gas and general-purpose piping applications. This fitting is installed by licensed plumbers, pipefitters, and mechanical contractors working on commercial or industrial pipe runs where a full-coupling connection is required.
This coupling is suited for 3-inch threaded pipe assemblies in gas distribution, water supply, compressed air, and general mechanical piping systems. Its black malleable iron construction makes it a common choice for above-ground gas piping per IFGC guidelines and for general industrial service. The fitting ships as a single unit and is sized to accept standard 3-inch male-threaded pipe ends on both sides.
Designed as an OEM-style replacement or standard fitting for 3-inch threaded malleable iron piping systems in plumbing, gas, and mechanical applications.
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 an appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten, as malleable iron threads can crack under excessive torque.
