The BMI USA 10571 is a black steel pipe nipple designed for joining threaded pipe sections in plumbing, gas distribution, and mechanical piping systems. Measuring 3/4 inch in diameter and 11 inches in length, this nipple provides a rigid, reliable threaded connection between fittings, valves, and pipe runs. The black finish is standard for gas piping applications and results from an oil-coating process applied during manufacturing. Licensed plumbers and pipefitters are the primary installers of this component in both residential and light commercial settings.
This pipe nipple is suited for use in natural gas, propane, and non-potable water piping systems where black steel is the specified material. Common applications include gas supply lines to appliances such as furnaces, boilers, water heaters, and ranges. It is also used in fire suppression system headers and industrial fluid distribution lines where steel construction is required by code or specification.
Designed as an OEM-style replacement and standard-stock pipe nipple compatible with 3/4 inch NPT threaded fittings, couplings, valves, and connectors used in residential and commercial gas and mechanical piping systems.
Installation of black steel pipe nipples in gas piping systems must comply with local codes and the International Fuel Gas Code (IFGC). A licensed plumber or pipefitter should perform or inspect all gas line connections. Apply an approved pipe thread sealant or PTFE tape rated for gas service to all threaded joints before assembly. Shut off the gas supply and verify zero pressure at the line before beginning any work on an existing system.
