The ASC Engineered Solutions 830045407 is a black steel pipe nipple sized at 3 inches by 3 inches, designed for use in threaded pipe assemblies across a range of commercial and industrial piping systems. This close or short nipple connects sections of threaded pipe where a rigid, corrosion-resistant black steel fitting is required. It is a standard trade component installed by licensed plumbers and pipefitters working on gas distribution, fire suppression, and general industrial piping applications.
This black steel nipple is suited for residential and commercial installations where threaded black steel pipe is specified. Common applications include natural gas and propane supply lines, steam systems, and industrial fluid transfer systems. The 3-inch diameter makes it appropriate for medium to large-bore piping runs typical in commercial mechanical rooms, industrial facilities, and larger residential gas service applications.
Designed as an OEM-style replacement or standard component for threaded black steel piping systems using 3-inch NPT connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Fuel Gas Code (IFGC) and International Plumbing Code (IPC) where required. Shut off gas or fluid supply and relieve system pressure before removing or installing any threaded fittings. Apply appropriate thread sealant rated for the intended service medium to all NPT threads before assembly. Do not overtighten threaded connections, as this can damage threads or cause leaks.
