The ASC Engineered Solutions 2D.BML is a 90-degree pipe elbow rated for 150 lb service, designed to redirect piping runs at a right angle in threaded pipe systems. Constructed from black malleable iron, it accepts 2.5-inch female NPT (FNPT) connections on both ends. Malleable iron provides the toughness needed to handle mechanical stress and vibration in demanding piping installations. This fitting is domestically produced and suits the rigorous requirements of gas, air, steam, and water distribution systems where threaded fittings are standard practice.
This elbow is used in residential and commercial mechanical systems including natural gas distribution, compressed air lines, steam piping, and hydronic heating. The 150 lb pressure rating makes it appropriate for low- to medium-pressure service applications. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting when routing threaded black iron pipe through walls, mechanical rooms, and utility spaces where a 90-degree direction change is required.
Designed as an OEM-style replacement and standard-service fitting for 2.5-inch threaded black iron pipe systems conforming to 150 lb malleable iron fitting standards.
Installation is performed by licensed plumbers or pipefitters following applicable code requirements such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the piping system fully before disassembling or installing any threaded fitting. Apply appropriate pipe thread sealant or PTFE tape to male threads before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.
