The BMI USA 10691 is a black steel pipe nipple sold in an assorted pack of 25 units, each measuring 1 inch in diameter and 6 inches in length. Black steel pipe nipples are threaded fittings used to connect sections of pipe or to attach pipe to valves, couplings, and other fittings in a piping system. The black finish indicates an uncoated carbon steel construction, making these nipples well suited for gas distribution, steam, and industrial fluid applications. Licensed plumbers and pipefitters install these as part of new construction and retrofit work.
These nipples are commonly used in residential and light commercial plumbing and gas piping systems. Typical applications include natural gas supply lines, steam distribution, and general industrial piping where a black steel fitting is required. The 25-count pack format is practical for service contractors and wholesale supply jobs requiring multiple connections at a single site or across multiple jobs.
Designed as an OEM-style replacement and standard fitment for 1 inch black steel threaded pipe systems in residential and commercial plumbing and gas piping applications.
Black steel pipe nipples are installed by licensed plumbers and pipefitters following applicable codes including the International Fuel Gas Code (IFGC) and International Plumbing Code (IPC). Shut off all gas or fluid supply and relieve system pressure before beginning work. Apply an approved thread sealant or PTFE tape rated for the service medium before threading the nipple into fittings. Inspect threads for damage before installation and do not use a nipple with stripped or cracked threads.
