The ASC Engineered Solutions 830034005 is a black steel close nipple measuring 1-1/2 inches in diameter by 5 inches in length. Black steel nipples are threaded pipe fittings used to connect sections of pipe or to join pipe to valves, couplings, and other fittings in gas, air, and industrial fluid distribution systems. This nipple is manufactured from black steel, which is standard for natural gas and propane distribution lines as well as non-potable water and compressed air applications. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this fitting type.
This fitting is suited for residential and light commercial piping systems where black steel is the specified material. Common applications include gas supply lines to furnaces, boilers, water heaters, and commercial cooking equipment, as well as compressed air distribution headers. The 1-1/2-inch trade size is frequently used in main gas supply runs and branch headers where moderate flow capacity is required. This is an import-sourced fitting intended for general-purpose piping work.
Designed as a standard replacement or new-installation nipple for 1-1/2-inch black steel piping systems using NPT threaded connections in residential and commercial gas, air, and industrial fluid distribution applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on the service. Shut off and verify zero pressure in the gas or fluid system before breaking any connection. Apply an approved thread sealant or pipe-thread compound rated for the intended service medium to all male threads before assembly. Do not use this fitting for potable water supply lines.
