The BMI USA 20106 is a 1-inch extra heavy black malleable iron pipe union designed for threaded pipe systems in demanding service environments. This union allows technicians to disconnect and reconnect pipe runs without cutting, making it a practical fitting for gas, steam, and mechanical piping installations. The extra heavy wall rating provides additional strength and durability over standard fittings, and the black finish is typical of fittings used in gas distribution and industrial piping. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this type of fitting.
This union is suited for use in residential and commercial piping systems where a threaded union connection is required. Common applications include gas supply lines, steam systems, and mechanical room piping where maintenance access and future serviceability are priorities. The 1-inch size fits standard Schedule 40 and extra heavy threaded pipe, making it a go-to component in boiler rooms, utility spaces, and industrial installations.
Designed as an OEM-style threaded union fitting for 1-inch extra heavy malleable iron piping systems in gas, steam, and mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC, and ASME B16.3 standards for malleable iron fittings. Shut off and depressurize the piping system completely before disassembling or installing this union. Apply appropriate thread sealant rated for the service medium — use thread compound or PTFE tape approved for gas service on gas lines. Do not overtighten the union nut; hand-snug plus a controlled wrench turn is standard practice for threaded malleable iron fittings.
