2 inch Galvanized Malleable Iron Tee – Threaded Fitting for Low-Pressure Piping Systems

The 2 inch Galvanized Malleable Iron Tee is designed for creating branch connections in threaded steel piping systems that convey water, air, steam, oil, or gas. With three female National Pipe Thread (NPT) ends, this fitting enables 90-degree diversion of flow while maintaining mechanical integrity in corrosive or humid environments.

Manufactured from ASTM A197 malleable iron and hot-dip galvanized to ASTM A153 standards, the corrosion-resistant zinc coating enhances service life in indoor or outdoor installations. This fitting is suitable for low- to medium-pressure applications where ferrous threaded systems are specified and soldering or welding is not feasible.

Technical Specifications

• Material: Galvanized malleable iron, ASTM A197
• Coating: Hot-dip galvanized, ASTM A153
• Size: 2-inch nominal pipe size (NPS)
• Ends: NPT female x NPT female x NPT female (ANSI B1.20.1)
• Pressure Rating: Class 150 (per ASME B16.3)
• Temperature Range: Typically -20°F to 300°F depending on media and sealing method

Performance Characteristics

• ✅ Three-Way Threaded Connection – Supports branch piping layouts in vertical or horizontal orientations.
• ✅ Corrosion-Resistant Finish – Zinc coating protects against atmospheric and water-induced corrosion in standard environments.
• ✅ Mechanical Strength – Malleable iron body allows for torque loads typical of steel pipe assembly without deformation.
• ✅ Standards Compliance – Conforms to ASME B16.3 and MSS-SP-79 for malleable iron threaded fittings.

Installation Notes

Use thread sealant (PTFE tape or thread compound) on male pipe threads before assembling the tee. Connections should be made hand-tight followed by wrench-tightening to specification. Avoid over-tightening to prevent cracking or thread deformation. For critical systems, hydrostatic testing is recommended after assembly.

Application Areas

Used in mechanical and plumbing systems for water distribution, compressed air lines, and low-pressure gas piping. Also suitable for general-purpose industrial piping in utility rooms, machine shops, and HVAC system layouts where galvanized protection is beneficial.

Compliance & Use Considerations

This fitting is not approved for potable water systems where local codes prohibit galvanized iron. It is suitable for non-potable water, HVAC hydronic loops, and fire protection branch lines (when permitted by local code). Consult project specifications and authority having jurisdiction (AHJ) for final approval.

The 2 inch Galvanized Iron Tee offers reliable, corrosion-resistant performance in threaded steel systems requiring a durable three-way branch fitting. Ideal for field installations requiring mechanical disassembly, long service life, and compatibility with standard ferrous piping.
