1-1/2 inch Galvanized Iron Tee – Threaded Fitting for Branch-Line Transitions in Water and Air Systems

The 1-1/2 inch Galvanized Iron Tee is a cast malleable iron fitting designed for use in threaded piping systems that require a three-way connection point. Its corrosion-resistant zinc coating makes it suitable for applications such as water distribution, compressed air, and non-potable fluid systems in both residential and commercial environments.

This tee features three female National Pipe Thread (NPT) connections, allowing a branch line to intersect a straight-run pipe at a 90-degree angle. It is manufactured to conform to ANSI and ASTM standards for malleable iron fittings, ensuring consistent thread engagement and structural performance under load.

Performance Features

• ✅ Material: Hot-dip galvanized malleable iron (ASTM A197)
• ✅ Connection Ends: Female NPT x Female NPT x Female NPT
• ✅ Thread Standard: ANSI/ASME B1.20.1
• ✅ Corrosion Protection: Zinc-coated surface for enhanced resistance to rust and oxidation in damp or humid conditions
• ✅ Pressure Rating: Typically up to 150 PSI for water, air, or oil systems depending on design parameters

Installation Considerations

Use thread sealant or PTFE tape on all mating threads to ensure leak-resistant joints. Avoid over-tightening to prevent cracking or damage to the threaded components. Ensure system alignment and apply torque evenly when integrating with other pipe sections. For horizontal installations, proper support spacing is critical to prevent undue stress on the tee.

Typical Applications

• Branch connections in domestic water distribution systems
• Air compressor line distribution
• Cooling system loops (non-potable)
• Industrial washdown and rinse piping
• Dry fire protection systems (non-potable applications only)

Code and Material Compliance

Complies with ASME B16.3 for malleable iron fittings and ASTM A153 for zinc galvanizing. Not suitable for underground installation without additional corrosion protection or for systems conveying potable water unless approved for specific code jurisdiction.

The 1-1/2 inch Galvanized Iron Tee is a durable, threaded solution for branch-line layout in mechanical and plumbing piping systems. Engineered for structural integrity and corrosion resistance in threaded system configurations requiring dependable three-way pipe transitions.
