BLK MAL TEE 2X1X2 – Black Malleable Iron Reducing Tee for Threaded Pipe Systems

The BLK MAL TEE 2X1X2 is a malleable iron reducing tee with female threaded ends, designed to facilitate a branch connection between 2", 1", and 2" nominal pipe sizes. It supports reductions within black iron piping systems used for gas, steam, air, and hydronic applications in both commercial and industrial environments.

Manufactured in accordance with ASTM A197 and threaded to ANSI B1.20.1 standards, this fitting offers high tensile strength and thermal stability. The corrosion-resistant black iron finish makes it suitable for above-ground installations where galvanized protection is not required. The reduced center outlet allows for efficient size transition without compromising system alignment or integrity.

Technical Features

• Material: Class 150 black malleable iron per ASTM A197
• End Connections: Female NPT (2" x 1" x 2")
• Pressure Rating: 150 PSI for steam and 300 PSI for non-shock cold water, oil, and gas systems
• Compliance: Conforms to ASME B16.3 and threads per ANSI B1.20.1
• Use Case: Allows pipe size reduction at branch intersections while maintaining flow direction and structural rigidity

Installation Considerations

Install with standard pipe wrenches. Apply thread sealant or PTFE tape compatible with the media being conveyed (gas, air, or water). Ensure torque is applied evenly to prevent stress fractures or misalignment. Final system pressure testing is recommended in accordance with applicable codes prior to system startup.

Common Applications

This reducing tee is used in black iron piping networks for heating loops, fuel gas lines, low-pressure steam distribution, and air compressor headers. It is especially useful where a smaller branch service is required off a main run without altering the larger line’s continuity.

Material Insight

Black malleable iron fittings are known for their strength, machinability, and thermal tolerance. They remain a staple in gas and mechanical systems where exposure to high heat or mechanical stress is routine, and where galvanized protection is either unnecessary or prohibited.
