1-1/2 inch x 1-1/4 inch Copper Reducing Tee – Precision-Fabricated for Professional Installations

The 1-1/2 inch x 1-1/4 inch Copper Reducing Tee is a sweat connection fitting engineered to transition between different pipe sizes in hydronic and potable water systems. Its design supports high-integrity joints, ideal for soldered connections in copper tubing networks where durability, flow optimization, and code compliance are non-negotiable.

Performance Attributes

• Material: Wrought copper, lead-free alloy in compliance with ASTM B75 and ANSI/NSF 61-G
• Connection Type: Female sweat (cup) x female sweat x female sweat
• Size: 1-1/2 inch nominal inlet x 1-1/4 inch nominal branch outlet
• Application: Used in Type L, M, and K copper tube systems for hot and cold water distribution, chilled water systems, and low-pressure steam

Key Advantages

• ✅ Uniform Wall Thickness for consistent heat distribution during soldering
• ✅ Precise Machining delivers optimal fit with minimal gaps for reduced joint failures
• ✅ Dezincification-Resistant for enhanced longevity in aggressive water conditions
• ✅ Code-Compliant—Conforms to ASME B16.22 and is certified lead-free under NSF/ANSI 372

Installation Considerations

This tee is designed for sweat soldering using standard plumbing torches and approved lead-free solder alloys. Ensure pipe ends are reamed and clean for full-depth insertion. Apply flux uniformly and heat appropriately for complete capillary action. Proper installation technique is critical to prevent cold joints or weeping under pressure.

Common Use Cases

This reducing tee is typically installed in domestic water supply branches, mechanical room risers, and utility systems where downsizing a main line to a secondary zone is required. Suitable for both vertical and horizontal configurations in copper piping layouts.

Did You Know?

All potable water plumbing systems are now required to use fittings that meet lead-free compliance standards across the U.S., making lead-free copper tees like this one essential for all code-approved installations.

Engineered for strength, reliability, and clean transitions, the 1-1/2 inch x 1-1/4 inch Copper Reducing Tee is a trusted component for demanding plumbing applications. Use it with confidence where system performance and code compliance are critical.
