The ASC Engineered Solutions 831037809 is a galvanized steel pipe nipple sized at 2 inches by 4 inches. Pipe nipples serve as short threaded connectors between fittings, valves, and pipe runs in fluid and gas distribution systems. This nipple is manufactured from galvanized steel, providing corrosion resistance suited for general-purpose piping applications. At 1.06 pounds, it is a solid, full-weight fitting appropriate for professional installations where quality and dimensional accuracy matter. Plumbers, pipefitters, and mechanical contractors rely on nipples like this to complete transitions and close-coupled connections throughout a system.
This nipple is used in residential and commercial plumbing, HVAC piping, and general mechanical systems where a 2-inch threaded connection with a 4-inch length is required. Typical applications include connecting valves to pipe headers, extending short runs between fittings, and completing assembly of water supply or distribution manifolds. The galvanized finish makes it suitable for exposed or mildly corrosive environments where bare steel would be at risk.
Designed as an OEM-style replacement or new-install fitting compatible with standard 2-inch NPT threaded pipe systems in plumbing and mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including IPC requirements. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly and tighten to hand-tight plus the number of turns appropriate for the pipe material and sealant type. Avoid over-tightening, which can crack fittings or damage threads.
