Black Iron Reducing Tee – Built for Pressure-Rated, Code-Compliant Transitions

The Black Iron Reducing Tee is designed to join three pipe segments of varying diameters in a branch configuration. Ideal for natural gas, LP, and hydronic applications, this tee provides a secure and durable connection capable of handling high-pressure conditions in both residential and commercial systems.

Manufactured from malleable black iron, this fitting delivers long-term performance where structural integrity and thermal resistance are critical. Its precise threading and corrosion-resistant finish make it a preferred choice for gas distribution and heating systems requiring dimensional accuracy and durability.

Key Performance Features

• Connection Type: Threaded (FPT x FPT x FPT)
• Body Material: Malleable Black Iron, conforming to ASTM A197
• Pressure Rating: Up to 300 psi (non-shock cold water, oil, and gas)
• Temperature Range: Suitable for elevated temperatures in steam and gas systems
• Finish: Protective black coating for oxidation resistance during transport and storage

Where It’s Typically Installed

• Natural gas and propane lines
• Hydronic heating loops
• Low-pressure steam distribution
• Compressed air systems (non-potable)

Installation Guidelines

This fitting is intended for use with threaded steel or black iron pipe. Apply pipe joint compound or PTFE tape on male threads to ensure a sealed, leak-free joint. Proper thread engagement and torque are essential—over-tightening may compromise joint integrity. Install in accordance with ASME B1.20.1 for standard pipe threads.

Did You Know?

Black iron fittings are not approved for potable water applications due to potential lead content and corrosion risk, but they remain a standard in fuel gas distribution because of their pressure capabilities and mechanical strength.

The Black Iron Reducing Tee is engineered to deliver robust, code-compliant connections for critical piping systems. With accurate sizing and durable threads, it supports reliable performance in high-demand applications—making it a dependable component for contractors who require consistency and safety in every install.
