Bmi 35405 Malleable Iron Tee Black 0.75 Inches

Product Description

The BMI 35405 is a 3/4-inch black malleable iron tee fitting designed for threaded pipe assemblies in gas, plumbing, and HVAC piping systems. Malleable iron construction provides the ductility and strength required to handle mechanical stress, vibration, and thermal cycling in demanding service environments. The black finish indicates an uncoated iron surface suited for gas distribution and low-pressure steam applications. This fitting is installed by licensed plumbers, pipefitters, and HVAC technicians working with Schedule 40 black iron pipe systems.

The BMI 35405 is commonly used in residential and light commercial gas supply lines, steam distribution headers, and general-purpose black iron pipe networks. The 3/4-inch tee configuration allows a branch takeoff from a main run of pipe, making it standard in gas manifold assemblies, boiler piping, and unit heater connections. Its threaded ends accept standard NPT male pipe threads for a secure, leak-resistant joint when properly sealed.

Key Features

• 3/4-inch NPT threaded connections on all three ports
• Malleable iron construction for strength and resistance to mechanical stress
• Black finish suitable for gas piping and low-pressure steam service
• Standard tee configuration for branch takeoffs in threaded pipe runs
• Lightweight at 0.234 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or standard fitting for 3/4-inch NPT black iron pipe systems used in gas, steam, and general plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, the International Fuel Gas Code (IFGC), and ASME B16.3 standards for malleable iron fittings. Shut off and lock out the gas or fluid supply before beginning any work on the piping system. Apply an approved pipe thread sealant or PTFE tape rated for the service medium to all threaded joints before assembly. Do not overtighten threaded connections, as malleable iron threads can crack under excessive force.
