The ASC Engineered Solutions 818902579 is a 2-inch black malleable iron male plug designed to cap or close off threaded pipe openings in a wide range of piping systems. Constructed from malleable iron with a black coating, this plug provides reliable thread engagement and a secure seal in applications where a pipe end must be temporarily or permanently closed. It is a standard threaded fitting used by plumbers, pipefitters, and HVAC mechanics on commercial and residential installations.
This fitting is suited for use in gas piping, steam, air, and water distribution systems where malleable iron fittings are specified. The black coating is standard for gas-rated piping assemblies and is commonly used in interior rough-in work. Installers typically pair this plug with compatible black malleable iron pipe and fittings to complete a threaded piping system.
Designed as an OEM-style replacement or standard fitting for use in 2-inch threaded black malleable iron piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code as required by the application. Apply an approved thread sealant or PTFE tape to the male threads before installation. Shut off and depressurize the piping system before removing or installing any threaded fittings. Do not overtighten, as malleable iron threads can be damaged by excessive force.
