1-1/2 inch x 1-1/4 inch x 1-1/2 inch Copper Reducing Tee – For Main Line Transitions with Reduced Branch

The 1-1/2 inch x 1-1/4 inch x 1-1/2 inch Copper Reducing Tee is designed for branching a reduced outlet from full-size main lines in copper tube systems. This fitting supports solder (sweat) connections and is suitable for use in pressure-rated potable water systems, hydronic distribution, and general mechanical piping applications.

Fabricated from lead-free copper in accordance with ASTM B88 standards, the tee is compatible with Type L and Type M copper tubing and meets ANSI/NSF 61-G for use in drinking water systems. Its reducing configuration is ideal for installations requiring a 1-1/4 inch branch connection off a 1-1/2 inch main line.

Key Features

• ✅ Lead-Free Copper Construction – Approved for use in potable water systems under the Safe Drinking Water Act.
• ✅ Uniform Socket Depths – Precision-machined for even capillary action during soldering, promoting long-term joint strength.
• ✅ Corrosion Resistance – Maintains integrity in systems exposed to varying pH and water conditions.
• ✅ Compact Tee Body – Supports tight installations in mechanical rooms and wall cavities without excess bulk.

Technical Specifications

• Nominal Sizes: 1-1/2 inch x 1-1/4 inch x 1-1/2 inch
• Material: Lead-Free Copper (ASTM B88)
• Connection Type: Sweat (Copper x Copper x Copper)
• Certifications: ANSI/NSF 61-G, Lead-Free Compliant

Installation Requirements

This fitting is intended for sweat installation using standard copper soldering practices. Pipe ends and fitting sockets must be reamed, cleaned, and fluxed prior to assembly. Uniform heating is necessary to ensure full solder penetration. Pressure testing should follow all installations, per local code requirements. Thread sealants or tapes are not applicable for solder connections.

Common Applications

Used in water distribution networks, fixture branch connections, and mechanical pipe layouts requiring a mid-run size transition. Frequently specified in residential and light commercial construction where consistent flow and dimensional accuracy are critical.

Regulatory Compliance

Conforms to federal and state regulations for lead-free plumbing materials. Certified for potable water use in all U.S. jurisdictions.

The 1-1/2 inch x 1-1/4 inch x 1-1/2 inch Copper Reducing Tee provides a durable, code-compliant solution for professionals working in mixed-diameter copper piping systems. Its precision-formed construction supports efficient layout designs and long-term performance in high-use plumbing environments.
