The ASC ENGINEERED SOLUTIONS 831029004 is a galvanized steel pipe nipple used to connect sections of threaded pipe in plumbing, HVAC, and industrial piping systems. Measuring 1-1/4 inches in diameter and 3-1/2 inches in length, this nipple provides a short, rigid threaded connection between fittings, valves, or pipe runs. It is constructed from galvanized steel, which resists corrosion in standard water and air service applications. Licensed plumbers and pipefitters are the primary installers, though HVAC mechanics and general contractors routinely use nipples of this type when assembling or repairing threaded pipe assemblies.
This nipple is suited for residential and light commercial piping applications where a 1-1/4-inch threaded connection is required. Common uses include water supply lines, gas distribution piping, compressed air lines, and hydronic heating systems. The 3-1/2-inch length makes it useful where a short extension or close offset is needed between two threaded fittings or valves.
Designed as an OEM-style replacement or standard-stock threaded nipple for use with 1-1/4-inch NPT threaded fittings, valves, and pipe couplings in typical plumbing and piping assemblies.
Installation is typically performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements for the service type. Shut off and depressurize the line before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Use a pipe wrench on the hex or body of adjacent fittings to avoid overstressing the nipple during tightening.
