1-1/4” x 3/4” x 1-1/4” Copper Reducing Tee – Wrot Copper Fitting for Pressurized and Non-Pressurized Piping Systems

The 1-1/4” x 3/4” x 1-1/4” Copper Reducing Tee is a solder joint fitting used to create a branch connection between copper tubing of dissimilar diameters. Manufactured from ASTM B75 Alloy C12200 (deoxidized, high phosphorus copper), it supports reliable capillary connections in hot and cold water distribution systems, hydronic heating loops, and closed-loop mechanical systems.

This tee conforms to ASME B16.22 dimensional standards and is designed with a center branch (3/4 inch) and two straight-run ends (1-1/4 inch) to facilitate directional changes and pipe reductions within a single fitting. The long-radius configuration reduces turbulence and pressure loss, improving overall system efficiency.

Product Features

• ✅ Material: Wrought copper (C12200, lead-free)
• ✅ Nominal Sizes: 1-1/4” x 3/4” x 1-1/4”
• ✅ Connection: Solder cups on all ends for capillary soldering
• ✅ Compliance: Meets ASME B16.22, NSF/ANSI 61 & 372 for potable water applications
• ✅ Applications: Potable water, chilled water, hydronic heating, and drainage systems

Installation Guidelines

Clean and deburr tubing ends prior to insertion. Apply approved flux and use lead-free solder per ASTM B813 and B828 standards. Ensure uniform heat distribution to facilitate solder draw throughout the joint. Support piping per code to prevent movement during cooling. Not intended for use in fuel gas systems unless otherwise approved.

System Use Cases

Used in both residential and commercial systems, this reducing tee is ideal for creating branches in supply loops, mixing circuits, or reducing lines within compact layouts. Common in manifold assemblies, vertical risers, and lateral runs requiring directional changes with integrated size reduction.

Regulatory Notes

This fitting is compliant with U.S. Safe Drinking Water Act lead-free provisions and certified for use in potable water systems. It also meets Uniform Plumbing Code (UPC) and International Plumbing Code (IPC) installation requirements for soldered copper fittings.
