1-1/4 inch x 1-1/4 inch x 1/2 inch Copper Reducing Tee – Sweat Connection for Potable Water Systems

The 1-1/4 inch Copper Reducing Tee is a wrot copper fitting designed for joining three copper tube sections of varying diameters. It features two 1-1/4 inch outlets and one 1/2 inch reducing branch, all with sweat (solder) connections, suitable for Type L and M copper tubing. Manufactured to ANSI/ASME B16.22 standards, this tee is commonly used in pressure-rated potable water systems and mechanical piping applications.

Made from lead-free alloy per ASTM B75 and compliant with NSF/ANSI 61 and 372 certifications, this fitting supports use in drinking water distribution and other systems requiring compliance with federal and local low-lead regulations. Its smooth bore design minimizes flow resistance, promoting efficient system operation.

Performance and Dimensional Specifications

• ✅ Material: Wrot copper (C12200)
• ✅ Main Run Size: 1-1/4 inch x 1-1/4 inch
• ✅ Branch Size: 1/2 inch
• ✅ Connection Type: Sweat (solder cup)
• ✅ Standard Compliance: ANSI/ASME B16.22, ASTM B75, NSF/ANSI 61 & 372
• ✅ Operating Pressure: Up to 200 PSI (depending on tubing type and application)

Application Scope

This reducing tee is suitable for installations requiring branch lines off larger copper distribution piping. Typical use cases include:

• ✅ Residential and commercial domestic water systems
• ✅ Hydronic heating systems
• ✅ Chilled water or HVAC loop installations
• ✅ Transition points to appliances, branch valves, or manifolds

Installation Considerations

All connections are designed for soldering with standard lead-free plumbing-grade solders. Surfaces must be cleaned and fluxed prior to assembly. Ensure proper heating for full solder penetration and bond strength. Use of a heat shield is recommended when working near flammable or finished surfaces.

Design Advantages

• ✅ Compact Form Factor: Ideal for concealed spaces such as wall cavities and floor joists
• ✅ Dezincification-Resistant: Material is not susceptible to zinc leaching, preserving integrity over time
• ✅ Consistent Wall Thickness: Manufactured for balanced heat transfer during soldering
• ✅ Low Pressure Drop: Smooth interior helps maintain system efficiency and reduces turbulence

Regulatory Note

Meets U.S. Safe Drinking Water Act requirements for lead-free plumbing products. Confirm use in accordance with applicable plumbing code jurisdictions.

The 1-1/4 inch x 1-1/4 inch x 1/2 inch Copper Reducing Tee offers reliable performance for pressure-rated copper systems, enabling clean transitions with reduced flow interruption. Its precise dimensions and code compliance make it an ideal choice for professional-grade installations in potable water or mechanical piping networks.
