The ASC ENGINEERED SOLUTIONS 831054002 is a galvanized steel pipe nipple used to connect or extend threaded pipe runs in plumbing, HVAC, and industrial piping systems. Measuring 4 inches in diameter by 5.5 inches in length, this nipple is manufactured from galvanized steel for corrosion resistance in standard service environments. It weighs 3.92 pounds per unit. Licensed plumbers and pipefitters install this type of fitting as part of threaded pipe assemblies in both commercial and residential applications.
This nipple is suited for use in water supply, gas distribution, or general-purpose piping systems that call for a 4-inch threaded connection. The 5.5-inch body length provides enough thread engagement and clearance for standard pipe unions, valves, and fittings. It is commonly used in mechanical rooms, boiler rooms, and industrial installations where a short close nipple or extension is needed between fittings or equipment connections.
Designed as a standard-thread replacement or new-install nipple for 4-inch NPT threaded piping systems in plumbing and mechanical applications.
Installation of 4-inch threaded pipe nipples should be performed by a licensed plumber or pipefitter. Shut off and depressurize the line before disassembly or installation. Apply an appropriate thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus wrench-tight per the applicable IPC or IFGC requirements for the service fluid. Do not over-tighten, as this can crack fittings or strip threads on galvanized steel.
