The ASC Engineered Solutions 830040606 is a black steel pipe nipple used to connect threaded pipe sections in gas, air, and general-purpose piping systems. Measuring 3 inches by 11 inches, this close-cut nipple provides a reliable, rigid connection between fittings, valves, or pipe runs. The black steel construction makes it well suited for gas distribution, industrial air lines, and non-potable water applications. Licensed plumbers, pipefitters, and mechanical contractors install this type of nipple as part of rough-in and service work on low- to medium-pressure systems.
This nipple is intended for use in commercial and residential piping systems where a threaded steel fitting is required. Common applications include natural gas and propane supply lines, compressed air distribution, and fire sprinkler support piping. The 3-inch by 11-inch size fits standard schedules of threaded black steel pipe and is typically used where a short to mid-length rigid connection is needed between two threaded components in a system.
Designed as an OEM-style replacement and standard-fit nipple for 3-inch NPT threaded black steel piping systems in residential and commercial mechanical applications.
Installation is performed by licensed plumbers or pipefitters following applicable code requirements such as the IFGC or IPC. Shut off and depressurize the system completely before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape rated for the intended service medium before making up the joint. Do not over-tighten threaded connections, as this can damage threads or crack adjacent fittings.
