Mueller W01064 1-5/8 x 1-3/8 Coupling

The Mueller W01064 1-5/8 x 1-3/8 Copper CxC Coupling is a high-performance reducing coupling engineered for professional HVACR and mechanical piping systems. This wrot copper fitting provides a reliable, permanent connection between 1-5/8" and 1-3/8" outside diameter tubing through a copper sweat coupling interface. Manufactured from high-grade UNS C12200 alloy, this component meets stringent ASME B16.22 standards for pressure and temperature performance in demanding refrigeration environments. The CxC (copper-to-copper) design ensures a consistent internal diameter flow, minimizing pressure drop across the transition. Designed for both residential and commercial potable water systems and high-pressure refrigeration lines, this fitting is rated for high-pressure applications and is compatible with modern refrigerants. For technicians in the field, the Mueller Streamline W01064 offers the thermal conductivity and corrosion resistance required for long-term system integrity without the risk of leak paths common in sub-standard alternatives.

• Precision Engineering: Manufactured to ASME B16.22 specifications for a perfect CxC coupling fit every time.
• High-Pressure Ready: Suitable for modern HVACR applications and potable water systems requiring durable copper fittings.
• Superior Material: Constructed from 99.9% pure UNS C12200 wrot copper for maximum corrosion resistance and thermal efficiency.
• Seamless Transition: Specifically designed as an HVAC copper reducer to bridge 1-5/8 inch and 1-3/8 inch piping without compromising flow.
