3 inch x 2 inch Copper Reducing Coupling Lead-Free Copper x Copper

3 inch x 2 inch Copper Reducing Coupling – Precision Fit for Pressure and DWV Systems

The 3 inch x 2 inch Copper Reducing Coupling is designed to provide a seamless transition between different copper pipe sizes while maintaining system integrity. Manufactured from high-purity, lead-free wrought copper, this coupling is engineered for use in both pressure applications and DWV (Drain, Waste, and Vent) systems.

Key Features

• Material: Wrought copper (ASTM B75/B88), lead-free for potable water use
• Size: 3 inch x 2 inch nominal tubing
• Connection Type: Cup (sweat) x Cup for soldered joints
• Application: Suitable for pressure piping, hydronic heating, and DWV transitions
• Temperature & Pressure Ratings: Up to 400 psi and 200°F, dependent on tubing and installation method

Performance Benefits

• Uniform Wall Thickness: Ensures consistent heat distribution during soldering for strong, leak-resistant joints
• Corrosion Resistance: Naturally resistant to mineral buildup and internal corrosion, improving system longevity
• Compact Profile: Ideal for tight areas where space constraints require minimal fitting bulk
• Industry Standards: Complies with ASME B16.22 and NSF/ANSI 61 certifications for potable water applications

Typical Applications

This coupling is used extensively in residential, commercial, and institutional construction. Common applications include water supply lines, boiler systems, and gravity-based DWV systems requiring a step-down transition between pipe sizes.

Installation Guidelines

For optimal performance, the coupling should be installed using industry-standard soldering practices. Ensure pipe ends are cleaned and fluxed properly prior to heating. Apply solder uniformly to achieve a full circumferential seal.

Did You Know?

Copper fittings such as this one are not only code-compliant but also offer antimicrobial properties, which can be beneficial in potable water systems by reducing microbial contamination over time.

Choose the 3 inch x 2 inch Copper Reducing Coupling for high-integrity pipe transitions that meet modern performance and safety expectations. Built for professional installations, this fitting supports clean, code-compliant construction across a wide range of plumbing environments.
