The ASC Engineered Solutions 812508612 is a black malleable iron union fitting sized at 1 inch. Unions allow piping sections to be connected and disconnected without disturbing the rest of the run, making them essential for serviceability in gas, steam, and general industrial piping systems. This fitting carries a black coating finish typical of gas-rated malleable iron fittings and is manufactured as an import product. Plumbers, pipefitters, and mechanical contractors install this type of union where future access or equipment removal is anticipated in the piping layout.
This union is suited for residential and light commercial piping applications including natural gas supply lines, steam distribution, compressed air, and similar services where malleable iron fittings are specified. Its 1-inch size fits standard schedule pipe and threaded fittings of the same nominal diameter, making it a common choice in boiler rooms, mechanical rooms, and utility service connections.
Designed as an OEM-style replacement or new-installation fitting compatible with 1-inch NPT threaded malleable iron piping systems used in gas, steam, and general mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or ASME B31 standards as required by the service. Shut off and bleed down the gas or steam supply before disassembling or installing any union fitting. Apply listed pipe thread sealant rated for the intended service to all threaded connections. Tighten the union nut securely but avoid over-torquing malleable iron threads.
