The ASC Engineered Solutions 812509206 is a 2-inch black malleable iron union designed for threaded pipe assembly and disassembly in pressurized piping systems. Malleable iron construction gives this union the strength and ductility needed to handle mechanical stress in demanding installations. The black coating provides corrosion resistance suitable for gas, steam, and water distribution applications. This fitting is installed by licensed plumbers, pipefitters, and HVAC technicians working on commercial and residential mechanical systems where frequent service access or section removal may be required.
This union is suited for 2-inch threaded piping systems in residential and light commercial installations. Typical applications include natural gas distribution lines, steam piping, compressed air systems, and potable or non-potable water lines. The three-piece union design allows sections of pipe to be disconnected without rotating the adjacent pipe segments, making it a practical choice for maintenance-heavy systems or equipment connections.
Designed as an OEM-style replacement or new-installation fitting for 2-inch threaded malleable iron piping systems in residential and commercial mechanical applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code, and the International Fuel Gas Code where applicable. Shut off and depressurize the supply line completely before removing or installing any union fitting. Apply appropriate pipe thread sealant or PTFE tape to all male threads before assembly, and tighten the union nut to a firm, leak-free connection without overtightening malleable iron threads.
