1-1/4 inch x 1 inch Copper Reducing Tee – Engineered for Code-Compliant Branching Transitions

The 1-1/4 inch x 1 inch copper reducing tee is purpose-built for delivering smooth, reliable transitions within pressurized water distribution systems. This fitting is ideal for use where a change in pipe size is required while maintaining directional flow across three branches—such as branch line takeoffs or fixture group reductions in residential and commercial copper piping networks.

Advantages of Using Precision Copper Tees

• ✅ ASTM B75/B88 Compliant Copper – Manufactured from high-purity, lead-free wrought copper for potable water safety and long-term corrosion resistance.
• ✅ Socket Ends for Soldering – Designed with sweat (cup) connections to allow clean, secure joins using standard soldering techniques.
• ✅ Pressure-Rated Design – Capable of withstanding working pressures in excess of 200 PSI at ambient temperatures, depending on pipe schedule and system configuration.
• ✅ Uniform Wall Thickness – Supports consistent heat transfer during soldering and promotes balanced hydraulic performance.

Technical Specifications

• Material: Wrought copper, lead-free
• End Connections: Copper x Copper x Copper (all sweat/solder)
• Nominal Sizes: 1-1/4 inch main run x 1 inch outlet
• Standards: ASME B16.22, NSF/ANSI 61 and NSF 372 for potable water use

Installation Notes

This tee is intended for soldered installation using ASTM B813-compliant water-soluble flux and lead-free solder. Pipe ends should be cleaned and deburred before assembly. Proper heat distribution and inspection are critical to ensure full circumferential bond strength. Always follow local code requirements for joint testing and pressure verification after installation.

Typical Applications

Used in copper Type L or Type M piping systems for domestic water, chilled water, and hydronic heating lines. Commonly installed behind walls, in ceiling drops, and manifold branches where a main run transitions into a smaller outlet line.

Code Compliance Reminder

As of the Federal Reduction of Lead in Drinking Water Act, all fittings used in potable systems must meet NSF/ANSI 372 requirements for lead-free construction. This tee meets or exceeds those mandates for safety and performance.

Engineered to meet the high demands of professional installations, this 1-1/4 inch x 1 inch copper reducing tee offers consistent results in new construction, retrofits, and code-driven upgrades.
