The ASC Engineered Solutions 8700133302 is a 1-1/2 inch malleable black iron coupling designed to join two pipes running in the same direction. Malleable iron construction provides the tensile strength needed for threaded pipe systems in demanding trade applications. This coupling is a standard inline fitting used by plumbers, pipefitters, and mechanical contractors working on gas distribution, fire suppression, compressed air, and water piping systems. Its black iron finish makes it suitable for use in non-corrosive dry piping environments where galvanized fittings are not required.
This coupling is suited for residential and light commercial piping installations where a reliable inline pipe connection is needed. Typical applications include natural gas supply lines, propane distribution, and general industrial pipe runs. It accepts standard NPT-threaded pipe on both ends, making it compatible with common pipe materials and system configurations encountered in everyday trade work.
Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch NPT-threaded malleable iron pipe systems in residential and commercial plumbing, gas, and mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Plumbing Code and International Fuel Gas Code where relevant. Shut off gas or fluid supply and depressurize the line before threading or removing any fittings. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
