The ASC Engineered Solutions 831037403 is a galvanized steel close nipple designed for use in threaded pipe systems across plumbing, HVAC, and industrial piping applications. Measuring 2 inches in diameter by 3 inches in length and weighing 0.76 pounds, this nipple provides a short, rigid threaded connection between fittings, valves, or pipe sections. The hot-dip galvanized coating offers corrosion resistance in wet or humid environments. Licensed plumbers and pipefitters handle installation as part of standard threaded pipe assemblies.
This nipple is suited for residential and light commercial piping systems where a compact, threaded connection is required. Typical applications include connecting valves, unions, tees, and elbows in water supply, hydronic heating, and general service piping. The 2-inch nominal size makes it appropriate for main distribution lines and larger branch connections in both new construction and retrofit work.
Designed as an OEM-style replacement or new-installation component for standard 2-inch NPT threaded pipe systems in plumbing, HVAC hydronic, and general industrial service applications.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the pipe system fully before disassembling any threaded connections. Apply thread sealant tape or pipe dope to the male threads before assembly and tighten to hand-tight plus wrench turns as appropriate for the fitting material. Avoid overtightening, which can crack fittings or distort threads.
