3 inch x 2 inch Copper Reducing Coupling – For Code-Compliant Pipe Size Transitions

The 3 inch x 2 inch Copper Reducing Coupling is a precision-engineered fitting designed for sweat connections between copper pipes of unequal diameters. Commonly used in pressure-rated potable water and mechanical piping systems, this fitting facilitates smooth hydraulic transitions while maintaining system integrity and dimensional stability.

Manufactured from lead-free copper alloy in compliance with ASTM B88 and ANSI/NSF 61-G standards, the coupling ensures compatibility with Type L and Type M copper tubing. Its consistent wall thickness and socket depth support uniform capillary solder joints for long-term, leak-resistant performance.

Key Performance Characteristics

• ✅ Precision Socket Dimensions – Allows for accurate alignment and full insertion depth for capillary bonding.
• ✅ Corrosion-Resistant Copper – Suitable for a variety of water chemistry and thermal cycling environments.
• ✅ Flow Transition Efficiency – Smooth internal bore reduces turbulence and pressure drop at reduction points.

Technical Specifications

• Material: Lead-Free Copper (ASTM B88 compliant)
• Nominal Sizes: 3 inch x 2 inch
• Connection Type: Copper x Copper (Sweat/Solder)
• Certifications: ANSI/NSF 61-G; Safe Drinking Water Act compliant

Installation Requirements

This fitting is intended for soldered connections. All pipe ends and sockets must be properly reamed, cleaned, and fluxed. Use of uniform heat is required to ensure full solder flow and joint penetration. System testing should be performed according to applicable code requirements following installation. Not compatible with threaded or mechanical connection methods.

Typical Applications

Used in potable water mains, hydronic distribution, and mechanical branches where size reduction is necessary within copper systems. Common in residential and light commercial settings, particularly in distribution headers, riser transitions, and pipe reroutes.

Regulatory Compliance

Manufactured in accordance with federal lead-free requirements and approved for use in all U.S. jurisdictions that mandate compliance with the Safe Drinking Water Act and local plumbing codes.

The 3 inch x 2 inch Copper Reducing Coupling is a reliable solution for professionals requiring a compact, durable, and code-compliant fitting for reducing copper tube sizes. Its construction and performance characteristics make it a dependable choice in high-demand installations.
