The BMI USA 10690 is a black steel pipe nipple sold in an assorted pack of 66 pieces, each measuring 1 inch in diameter and 6 inches in length. Black steel pipe nipples are close-coupled threaded fittings used to connect sections of pipe or join pipe to valves, fittings, and equipment in gas, steam, and industrial fluid systems. The black finish indicates the absence of galvanizing, making these nipples standard for natural gas and propane distribution lines as well as fire suppression and general industrial piping. The pack weight of 26.93 pounds reflects a bulk-quantity format suited for service vehicles, shop stock, or project staging.
These nipples are used in residential and commercial plumbing and mechanical systems where black steel pipe is the specified material. Typical applications include gas supply lines, steam distribution, and industrial process piping. The 6-inch length and 1-inch diameter make this a common size for branch connections, riser assemblies, and equipment connections. The 66-piece assorted pack format is well suited for contractors and service technicians who maintain working inventories of commonly needed nipple sizes.
Designed as an OEM-style replacement and standard stock fitting for 1-inch black steel pipe systems using NPT threaded connections in gas, steam, and industrial piping applications.
Black steel pipe nipples are installed by licensed plumbers or pipefitters following applicable code requirements such as the IFGC or IPC. Shut off and depressurize the line before removing or installing any threaded fittings. Apply appropriate thread sealant or tape rated for the intended service medium before making up connections. Inspect threads for damage before installation and do not force cross-threaded connections.
