1-1/2 inch x 3/4 inch Copper Reducing Coupling – Built for System Integrity and Longevity

The 1-1/2 inch x 3/4 inch Copper Reducing Coupling is designed for efficient transitions between dissimilar pipe sizes in copper tubing systems. Engineered for compatibility with sweat connections, this fitting ensures a smooth, leak-resistant transition that supports optimal flow and long-term performance in potable water, hydronic, or HVAC applications.

Professional-Grade Benefits

• ✅ Lead-Free Copper Construction – Meets federal and state lead reduction mandates for use in potable water systems.
• ✅ Uniform Wall Thickness – Helps ensure thermal transfer balance and consistent joint strength under high-temperature soldering.
• ✅ Accurate Sizing – Sized in accordance with ASTM B88 standards, supporting reliable connections with Type L and M copper tubing.
• ✅ Sweat Connections – Suitable for use with soldered joints, offering a strong, permanent seal when properly installed with flux and solder.
• ✅ Code Compliant – Complies with applicable plumbing codes including IPC, UPC, and NSF 61/372 for potable applications.

Common Applications

This reducing coupling is utilized in systems requiring a size transition without compromising flow efficiency. Typical installations include:

• Water distribution systems (hot and cold)
• Closed-loop hydronic heating
• Chilled water loops in HVAC systems
• Potable water supply lines

Installation Guidance

Installation is straightforward for qualified professionals. Use of emery cloth or wire brush is recommended for surface prep prior to soldering. Always apply lead-free solder and NSF-approved flux for safe, code-compliant joints. Avoid over-heating to maintain structural and sealing integrity of the fitting.

Technical Specifications

• Material: Wrot copper, lead-free
• Nominal Sizes: 1-1/2 inch x 3/4 inch
• Connection Type: Copper x Copper (sweat)
• Standards: ASME B16.22, NSF/ANSI 61 & 372, ASTM B75 & B88

Note:

Proper installation practices are essential. For systems under pressure or with thermal cycling, joint integrity depends on skilled soldering and thorough preparation. Do not use in compressed air systems or gas lines unless specifically rated.

When system reliability and regulatory compliance matter, trust the 1-1/2 inch x 3/4 inch Copper Reducing Coupling to deliver a high-performance, permanent solution that meets the demands of professional-grade plumbing installations.
