The ASC ENGINEERED SOLUTIONS 831019807 is a galvanized steel close nipple measuring 3/4 inch by 3 inches. It is a short threaded pipe fitting used to connect two female-threaded components in plumbing, HVAC piping, and general mechanical systems. The galvanized steel construction provides corrosion resistance for water and gas distribution lines. Plumbers and pipefitters install this type of nipple during new construction, system repairs, and retrofit work where a compact threaded connection is required.
This nipple is suited for residential and light commercial piping applications including water supply lines, natural gas distribution, compressed air systems, and hydronic heating runs. Its 3/4 inch nominal pipe size makes it a common fit in branch connections and service drops. The 3-inch length provides enough thread engagement and clearance for most standard coupling and valve installations where a hex nipple would be too short.
Designed as a standard NPT-threaded replacement or new-installation nipple for 3/4 inch pipe systems in residential and commercial plumbing, HVAC piping, and mechanical gas distribution applications.
Installation is performed by licensed plumbers or pipefitters following applicable local plumbing codes and IFGC requirements for gas applications. Shut off the water supply or gas source and depressurize the line before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as this can crack fittings or damage mating threads.
