1-1/4 inch x 1 inch x 3/4 inch Copper Reducing Tee – For Multi-Diameter Copper Branch Connections

The 1-1/4 inch x 1 inch x 3/4 inch Copper Reducing Tee is engineered to facilitate pipe size transitions in copper distribution systems. Designed for sweat (soldered) installation, it provides a secure and code-compliant solution for joining three copper lines of different diameters within potable water or mechanical piping systems.

Fabricated from lead-free copper, the tee conforms to ANSI/NSF 61-G and ASTM B88 standards, making it suitable for use in pressure-rated and hydronic applications. Its reducing configuration allows for space-efficient layout designs and streamlined branching without additional fittings.

Key Product Features

• ✅ Multi-Size Configuration – Connects 1-1/4 inch, 1 inch, and 3/4 inch copper tubing in a single fitting.
• ✅ Lead-Free Copper Construction – Compliant with U.S. Safe Drinking Water Act and applicable state codes.
• ✅ Uniform Socket Dimensions – Supports full capillary solder penetration for a secure joint.
• ✅ Corrosion Resistance – Resilient against degradation in potable and non-potable systems.
• ✅ Compact Tee Profile – Allows for installation in confined areas, including wall cavities and equipment chases.

Technical Specifications

• Material: Lead-Free Copper (ASTM B88)
• Nominal Sizes: 1-1/4 inch x 1 inch x 3/4 inch
• Connection Type: Copper x Copper x Copper (Sweat)
• Certifications: ANSI/NSF 61-G; Lead-Free Compliant

Installation Guidance

This tee requires standard sweat installation procedures. Clean and deburr tubing ends before applying flux. Apply even torch heat to ensure full solder bond throughout the joint. Pressure testing is recommended after installation per local code requirements. This fitting is not intended for use with threaded or compression systems, and thread sealant or tape should not be used.

Typical Applications

Commonly used in potable water supply, mechanical loop branches, and fixture distribution systems. Ideal for new construction, system retrofits, and manifold assemblies requiring stepped pipe sizes within limited space constraints.

Compliance Note

All components are lead-free and certified for use in drinking water systems under federal and state regulations. Suitable for use in all jurisdictions requiring compliance with current plumbing codes.

The 1-1/4 inch x 1 inch x 3/4 inch Copper Reducing Tee offers a code-compliant, space-efficient solution for branching copper pipe systems across varying sizes. Designed for durability, ease of installation, and long-term reliability, it is a standard fitting for professionals working in high-performance plumbing environments.
