Bmi 35404 Malleable Iron Tee Black 1/2 Inch

Product Description

The BMI 35404 is a black malleable iron tee fitting sized at 1/2 inch, designed for threaded pipe assemblies in gas, plumbing, and industrial piping systems. Malleable iron construction provides the toughness and ductility required for standard threaded installations where vibration resistance and durability are critical. The black finish is standard for gas piping applications. Plumbers, pipefitters, and HVAC technicians install this fitting as part of branch connections in low-pressure piping runs. At 0.144 pounds, it is a compact, lightweight fitting suited for tight installations.

This tee fitting is used in residential and light commercial applications where a 1/2 inch branch takeoff is needed from a main pipe run. Typical installations include natural gas distribution lines, compressed air systems, water supply piping, and general-purpose industrial piping. The threaded female connections on all three ports accept standard NPT fittings, making it compatible with common black iron pipe, galvanized pipe, and other NPT-threaded components found in trade installations.

Key Features

• Black malleable iron construction provides ductility and vibration resistance in threaded pipe systems
• 1/2 inch port size fits standard NPT threaded pipe and fittings
• Black finish makes it appropriate for natural gas and fuel gas piping applications
• Lightweight at 0.144 pounds for easy handling and installation in confined spaces
• Three-port tee configuration allows branch connections off a main pipe run

Compatibility

Designed as an OEM-style replacement and standard trade fitting for 1/2 inch NPT threaded iron piping systems in gas, plumbing, and industrial applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable local codes and IFGC requirements for gas piping systems. Shut off and depressurize the pipe system before making or breaking any threaded connections. Apply thread sealant or PTFE tape rated for the intended service medium before threading fittings together. Do not overtighten threaded fittings, as malleable iron can crack under excessive torque.
