The ASC Engineered Solutions 830047007 is a black steel pipe nipple sized at 3 inches by 7 inches. Pipe nipples are short lengths of threaded pipe used to connect fittings, valves, and other components in a piping system. This nipple is manufactured from black steel, making it suitable for gas distribution, compressed air, and similar industrial or mechanical piping applications. Licensed plumbers, pipefitters, and mechanical contractors install these components during new construction and retrofit work. The 3-inch diameter and 7-inch length make it appropriate for larger-diameter runs where a close or hex nipple would be too short.
This black steel nipple is used in residential and commercial mechanical systems where threaded black iron or steel pipe is specified. Common applications include natural gas and propane supply lines, fire suppression systems, steam piping, and compressed air distribution. It is well-suited for interior rough-in work where corrosion resistance from coatings or galvanizing is not required by code. The 3-inch nominal pipe size positions this fitting in commercial and light industrial installations rather than typical residential lines.
Designed as a standard threaded replacement or new-installation fitting for black steel pipe systems using 3-inch nominal NPT connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and fuel gas codes, including the IFGC and IPC where adopted. Shut off the gas or fluid supply and depressurize the line before removing or installing any threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-torque threaded connections, as black steel pipe threads can crack or strip if excessive force is applied.
