The BMI USA 10665 is a black steel pipe nipple sized at 1 inch by 6.5 inches, designed for use in threaded pipe assemblies across plumbing, gas distribution, and mechanical systems. The black finish results from a hot-applied coating that provides corrosion resistance in dry or low-moisture environments. Constructed from steel, this nipple delivers the structural integrity and pressure tolerance that trade professionals expect in threaded iron pipe work. Licensed plumbers, pipefitters, and HVAC technicians routinely use nipples of this type to connect valves, fittings, and pipe runs in a wide range of service applications.
This nipple is suited for residential and light commercial installations where standard black iron pipe systems are specified. Common applications include natural gas supply lines, propane distribution, fire suppression headers, and general-purpose water or air piping where black steel is code-acceptable. The 1-inch diameter and 6.5-inch length make it a practical close-to-medium extension fitting in tight mechanical spaces or equipment connections.
Designed as an OEM-style replacement and standard component for 1-inch NPT threaded black iron pipe systems in gas, air, and general mechanical piping 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) as required by the service type. Shut off the gas or fluid supply and depressurize the line before threading or removing any fittings. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Do not overtighten threaded connections; use a pipe wrench with proper backup support to avoid stressing adjacent fittings.
