The ASC Engineered Solutions 310025200 is a 4-inch black malleable iron 45-degree elbow designed for use in threaded pipe systems. Malleable iron construction provides the ductility and strength required for pressurized piping applications, and the black coating offers corrosion resistance suitable for gas, air, and general industrial service. This fitting is domestically manufactured and weighs 7.40 pounds. It is installed by licensed plumbers, pipefitters, and mechanical contractors working on commercial or industrial piping assemblies.
This 45-degree elbow is suited for changing pipe direction in threaded black iron piping systems. Common applications include natural gas distribution, compressed air lines, steam systems, and general industrial fluid handling. The 4-inch size fits high-volume line runs where larger pipe diameters are required. Its black finish makes it a standard choice for above-grade gas piping per applicable code requirements.
Designed as an OEM-style threaded fitting for use with standard 4-inch black iron pipe in gas, air, steam, and general industrial piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and fuel gas codes such as the IFGC and ASME B31 standards. Shut off and depressurize the pipe system completely before disassembling any fittings. Apply listed thread sealant or PTFE tape to male threads before assembly and tighten to hand-snug before using a pipe wrench. Do not over-torque malleable iron fittings, as cracking can occur.
