Bmi Usa 36109 Galvanized Malleable Iron 2 in Pipe Union

Product Description

The BMI USA 36109 is a 2-inch galvanized malleable iron pipe union designed for joining and disconnecting threaded pipe runs in plumbing, HVAC, and mechanical piping systems. The galvanized finish provides corrosion resistance in exposed or damp environments. Malleable iron construction gives the fitting the durability and ductility needed to handle typical system vibration and thermal cycling. Licensed plumbers and pipefitters install this fitting where future serviceability is required, allowing a piping section to be broken and reconnected without cutting.

This union is suited for residential and light commercial piping applications where a threaded, demountable connection is needed. Common install scenarios include water supply lines, gas distribution piping, boiler connections, and mechanical room piping where routine maintenance access is anticipated. The galvanized finish makes it appropriate for applications where bare iron would be exposed to moisture or mild corrosive conditions.

Key Features

• Galvanized finish for corrosion resistance in damp or exposed environments
• Malleable iron construction for strength and ductility under vibration and thermal stress
• 2-inch pipe size for medium-diameter threaded piping systems
• Union design allows pipe disconnection without cutting or threading new pipe
• Threaded connection compatible with standard NPT pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch threaded galvanized or black iron piping systems in plumbing and mechanical applications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements for the service type. Shut off and depressurize the piping system fully before disassembling or installing the union. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly. Hand-tighten first, then wrench-tighten to a snug fit without over-torquing malleable iron threads.
