The ASC Engineered Solutions 830037800 is a black steel pipe nipple sized at 2 inches by 4 inches, designed for use in threaded piping systems across a range of commercial and industrial applications. Black steel nipples serve as short-length pipe connectors between fittings, valves, and other threaded components. This nipple is manufactured from black steel, which provides reliable strength in gas distribution, steam, and general-purpose piping systems. Licensed plumbers and pipefitters are the primary installers. At 1.06 pounds, the fitting is a standard close or short nipple form factor suited to tight-space installations.
This nipple is commonly used in gas supply lines, steam piping, compressed air systems, and industrial fluid distribution where black steel threaded fittings are specified. The 2-inch by 4-inch sizing fits standard NPT threaded configurations at that nominal pipe size. It is appropriate for both new construction and retrofit work in commercial mechanical rooms, boiler rooms, and similar environments where black iron or black steel piping is required by code or design.
Designed as an OEM-style replacement or standard-stock fitting for use with 2-inch NPT threaded piping systems utilizing black steel components.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off all gas or fluid supply and depressurize the line completely before removing or installing any threaded pipe fitting. Apply appropriate thread sealant or PTFE tape rated for the service fluid before threading the nipple into place. Do not over-tighten threaded connections, as this can damage fitting threads or cause joint failure.
