The ASC Engineered Solutions 830001400 is a black steel close nipple measuring 1/8 inch in diameter by 3-1/2 inches in length. This threaded pipe fitting is used to connect two female-threaded fittings or valves in a piping system. Black steel construction makes it appropriate for gas, oil, and steam applications in mechanical systems. Plumbers, pipefitters, and HVAC technicians install these as standard pipe make-up components where a short, fixed-length threaded connection is required. The part weighs 0.06 pounds and is sourced as an import product.
This nipple is suited for residential and light commercial piping installations where 1/8-inch NPT threaded connections are specified. Common applications include gas supply lines, low-pressure steam systems, and general plumbing rough-in work. The 3-1/2-inch body length provides enough thread engagement on both ends while leaving exposed pipe between fittings, making it useful where a close nipple would not reach and a longer nipple would be excessive.
Designed as a standard 1/8-inch NPT threaded pipe nipple for use with compatible black steel fittings, valves, and pipe in general mechanical, plumbing, and gas piping systems.
Installation is performed by licensed plumbers or pipefitters following applicable local codes including the IFGC for gas applications and the IPC for water and steam systems. Shut off all gas or fluid supply and relieve system pressure before disassembling or replacing any threaded pipe fitting. Apply approved thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections in black steel fittings, as this can crack adjacent cast fittings.
