The BMI USA 10235 is a black steel pipe nipple used to create threaded pipe connections in gas, water, and general plumbing distribution systems. Measuring 3.5 inches in length with a 0.25-inch nominal pipe size, this nipple serves as a short threaded connector between fittings, valves, and pipe assemblies. The black finish indicates it is mill-coated steel, the standard for natural gas and propane distribution lines as well as general industrial piping. Licensed plumbers and pipefitters install this type of fitting during rough-in and retrofit work across residential and light commercial applications.
This nipple is suited for threaded piping systems where a short, rigid connection is required between two fittings or between a fitting and a valve. Common applications include gas supply lines, compressed air headers, boiler piping, and general industrial plumbing assemblies. The black mill coating distinguishes it from galvanized fittings and makes it the correct choice for natural gas and propane service per standard installation practice.
Designed as an OEM-style replacement or standard stock nipple for 0.25-inch NPT threaded piping systems in residential and light commercial gas, water, and general plumbing applications.
Installation of threaded pipe nipples in gas service should be performed by a licensed plumber or pipefitter in accordance with local code and IFGC requirements. Shut off the gas or water supply and relieve system pressure before disassembling any threaded connection. Apply an appropriate thread sealant or listed pipe thread compound to the male threads before assembly. Do not use galvanized fittings in natural gas or propane service in place of black steel fittings.
