The ASC Engineered Solutions 830024808 is a black steel close nipple used to connect threaded pipe sections in gas, air, and fluid distribution systems. Sized at 1 inch by 4 inches, this import-grade fitting is manufactured from black steel, which provides the strength and thread integrity required for low-pressure gas lines, compressed air runs, and general industrial piping. It is installed by licensed plumbers, pipefitters, and HVAC technicians working on commercial and residential mechanical systems. The fitting weighs 0.47 pounds and is designed to accept standard NPT threaded connections on both ends.
This nipple is suited for use in threaded black iron or black steel piping systems where a short, fixed-length connection between two fittings or valves is required. Common install scenarios include gas supply lines, boiler piping, compressed air distribution headers, and industrial fluid handling. The 1-inch by 4-inch sizing makes it a frequently specified dimension for branch connections and equipment tie-ins in light commercial and residential mechanical rooms.
Designed as an OEM-style replacement or standard supply fitting for 1-inch threaded black steel piping systems in gas, air, and general industrial fluid service applications.
Installation is performed by licensed plumbers or pipefitters following applicable codes such as the IFGC or IPC depending on the service medium. Shut off and depressurize the line before removing or installing any threaded fitting. Apply an approved thread sealant or tape rated for the intended service medium to all male threads prior to assembly. Do not overtighten; use a pipe wrench and backup wrench to avoid stressing connected fittings or valves.
