3/4 inch x 1/2 inch Copper Reducing Coupling – Solder Joint Fitting for Water Distribution Systems

The 3/4 inch x 1/2 inch Copper Reducing Coupling is a sweat-type fitting used to join copper tubing of two different nominal sizes. Commonly installed in hot and cold potable water systems, this coupling allows for a direct, in-line reduction from 3/4-inch to 1/2-inch copper pipe, minimizing the need for additional transition fittings.

Manufactured from lead-free wrought copper in accordance with ASTM and ANSI standards, this fitting is suitable for soldered joints in residential, commercial, and institutional piping systems. It provides a durable, permanent connection when installed using approved soldering practices.

Key Product Features

• ✅ Wrought Copper Alloy: Fabricated from C12200 alloy per ASTM B75/B88 standards for strength and corrosion resistance.
• ✅ Socket x Socket Configuration: Accepts copper tubing on both ends for soldered (sweat) joints.
• ✅ Lead-Free Certified: Complies with NSF/ANSI 61 and 372 for potable water applications in compliance with the Safe Drinking Water Act.
• ✅ Compact Design: Supports efficient layout in tight mechanical spaces and clean transitions between line sizes.
• ✅ Code-Compliant: Meets ASME B16.22 for use in plumbing systems governed by IPC and UPC standards.

Technical Specifications

• Nominal Sizes: 3/4 inch x 1/2 inch
• Material: Lead-Free Wrought Copper (C12200)
• Connection Type: Solder (Copper x Copper)
• Applicable Standards: ASTM B75, ASME B16.22, NSF/ANSI 61 & 372

Installation Guidelines

This fitting is installed using soldering techniques. Prepare tubing ends by cleaning and deburring. Apply lead-free flux to the tube and fitting, assemble, and apply heat evenly until solder flows into the joint. Allow the joint to cool before applying pressure. Follow local code requirements and manufacturer recommendations for solder and flux compatibility.

Typical Applications

Used in water distribution lines, branch piping, and retrofit assemblies where a change in pipe diameter is needed. Suitable for concealed or exposed installations in copper plumbing systems found in residential or commercial buildings.

Code Compliance Note

All copper fittings used in potable water systems must be certified lead-free and conform to applicable plumbing code requirements. This fitting is compliant with low-lead mandates and approved for use in U.S. jurisdictions.

The 3/4 inch x 1/2 inch Copper Reducing Coupling provides a reliable, code-approved solution for size transitions in soldered copper pipe systems. Its compact design and standardized fabrication ensure consistent performance in pressure-rated water distribution networks.
