The ASC Engineered Solutions 830018404 is a black steel pipe nipple measuring 0.5 inches in diameter by 11 inches in length. This threaded fitting connects sections of steel pipe in gas, air, and fluid distribution systems. It is manufactured from black steel and sourced as an import product. Plumbers, pipefitters, and mechanical contractors install this type of nipple as a short extension or coupling connector in low-pressure piping assemblies. At 0.75 pounds, it is a standard-weight fitting suited for typical commercial and residential rough-in work.
This nipple is used in residential and light commercial piping applications including natural gas supply lines, compressed air distribution, and general-purpose black iron pipe systems. The 0.5-inch by 11-inch size fits standard NPT-threaded pipe runs where a close or short nipple does not provide enough extension. It is a common stocking item for plumbing rough-in, mechanical room builds, and gas appliance connections.
Designed as a standard black iron pipe nipple for use with 0.5-inch NPT-threaded fittings, valves, and pipe in residential and commercial mechanical piping systems.
Licensed plumbers and pipefitters typically install black steel nipples using pipe wrenches and appropriate thread sealant or PTFE tape rated for the service fluid. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Gas line installations must comply with the International Fuel Gas Code and applicable local codes, and work on gas systems should be performed by licensed professionals only. Avoid over-torquing threaded connections, which can crack fittings or strip threads.
