1-1/4” Copper Tee – High-Performance Fitting for Pressurized Water Systems

The 1-1/4” Copper Tee is engineered for branching copper tubing in potable water, hydronic heating, and other pressure systems. Fabricated from wrought copper, this tee ensures precise alignment and a reliable fit, promoting a smooth, leak-resistant flow path across all three connections.

This fitting meets ASTM and ANSI standards and is NSF certified for use in drinking water applications. It is ideal for solder connections in Type L and Type M copper installations, offering superior corrosion resistance and structural integrity in both residential and commercial systems.

Advantages of a Wrought Copper Tee

• ✅ Full-Flow Design – Allows for unrestricted water movement across all three branches.
• ✅ ASTM B75/B88 Compliance – Manufactured to meet stringent copper tube fitting standards.
• ✅ Lead-Free Construction – Safe for potable water distribution per the Safe Drinking Water Act.
• ✅ Excellent Corrosion Resistance – Maintains performance in demanding pressure and thermal environments.
• ✅ Uniform Wall Thickness – Enhances strength at stress points, particularly at branch intersections.

Application and Use

This tee is used to branch 1-1/4” copper lines in hot and cold potable water systems, chilled water loops, and low-pressure steam or HVAC circuits. It is frequently installed in mechanical rooms, riser trunks, and horizontal runs requiring mid-line outlet connections.

Installation Considerations

Install using standard soldering practices for copper tube. Clean all mating surfaces thoroughly, apply approved flux, and use lead-free solder for joint integrity. Always pressure test after assembly to confirm leak-free seals before system operation.

Did You Know?

Wrought copper fittings offer more consistent dimensions and wall thickness compared to cast alternatives, making them preferred for professional-grade installations subject to code enforcement and inspection.
