The ASC Engineered Solutions 810025205 is a 4-inch black malleable iron 45-degree elbow fitting used in threaded pipe systems across plumbing, mechanical, and industrial piping applications. The fitting is coated black and constructed from malleable iron for durability in demanding service conditions. At 6.92 pounds, this is a full-size fitting intended for permanent threaded connections in larger-diameter pipe runs. Licensed plumbers and pipefitters handle installation as part of new construction or repair work on threaded iron pipe systems.
This elbow is sized at 4 inches and is suited for use in commercial and industrial piping systems where a 45-degree directional change is required. It is commonly installed in gas distribution, steam, water, and general mechanical piping applications that call for standard threaded malleable iron fittings. The black coating makes it appropriate for gas piping where black iron is the standard specified material.
Designed as an OEM-style replacement or new-installation fitting for 4-inch threaded malleable iron pipe systems following standard NPT thread specifications.
Installation of this fitting should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Always shut off and depressurize the pipe system before disassembling or installing threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape rated for the intended service medium before threading the fitting onto the pipe. Do not overtighten, as malleable iron threads can be damaged by excessive torque beyond hand-tight plus standard wrench turns per trade practice.
