The ASC Engineered Solutions 830054201 is a black steel pipe nipple used to connect sections of threaded pipe in gas, industrial, and mechanical piping systems. This close-tolerance fitting measures 4 inches in diameter by 5.5 inches in length and weighs 3.92 pounds. Black steel construction makes it a standard choice for natural gas and propane distribution lines, fire suppression systems, and industrial fluid transport where corrosion protection from galvanizing is not required. It is typically installed by licensed plumbers, pipefitters, or HVAC technicians working on gas or mechanical piping assemblies.
This nipple is suited for residential and commercial applications where threaded black steel pipe is the specified material. Common install scenarios include branch connections at manifolds, riser extensions, and short-run connections between valves, unions, and fittings in gas distribution and hydronic heating systems. The 4-inch nominal size targets main-line or large-branch piping configurations typical in commercial mechanical rooms and industrial installations.
Designed as an OEM-style replacement and standard-stock fitting for threaded black steel piping systems using 4-inch nominal pipe size components.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where gas or fluid lines are involved. Shut off gas supply or isolate the system and relieve pressure before disassembling any existing piping. Use an appropriate thread sealant or PTFE tape rated for the service medium on all threaded connections. Inspect threads for damage before assembly to ensure a leak-free joint.
