1-1/4 inch x 1 inch x 1-1/4 inch Copper Reducing Tee – Solder Joint Fitting for Potable Water and Hydronic Systems

The 1-1/4 inch Copper Reducing Tee is engineered to provide a smooth, reliable branch connection in copper tube systems where a change in diameter is required. Manufactured from wrought copper (typically ASTM B75 or B88 tube), this tee features sweat (solder) ends for secure, permanent installation in Type L, M, or K copper piping systems.

This fitting is suitable for use in both residential and commercial plumbing installations, including domestic hot and cold water supply, hydronic heating, and chilled water applications. Its seamless design allows for streamlined flow, while its corrosion-resistant properties ensure long service life in both above-ground and in-wall applications.

Key Product Features

• Material: Wrought copper conforming to applicable ASTM standards
• Dimensions: 1-1/4 inch x 1 inch x 1-1/4 inch nominal tubing size
• Connection: Female solder (cup) ends
• Temperature Rating: Up to 400°F when properly soldered
• Pressure Rating: Up to 200 PSI for water systems
• Certifications: ANSI/NSF 61 and NSF 372 compliant (lead-free)

Installation Notes

This tee is designed for use with soldered copper connections. Prior to installation, ensure all mating surfaces are cleaned and properly fluxed. Apply heat evenly and introduce lead-free solder until a full capillary seal is achieved. Allow the joint to cool naturally before pressure testing. Always follow local code requirements and manufacturer guidelines for joining procedures.

Applications

Commonly used in:

• Potable water distribution networks
• Closed-loop hydronic heating systems
• Chilled water piping
• Branch takeoffs in distribution manifolds
• Multi-story domestic water risers requiring size transitions

Additional Considerations

Copper fittings provide inherent antimicrobial properties and are fully recyclable. The reducing branch in this configuration supports balanced system flow and optimizes space in dense mechanical runs. This product meets current U.S. lead-free plumbing standards for use in potable water systems.
