Mueller W01011 3/8 x 1/4 Coupling

The Mueller W01011 3/8 x 1/4 Copper CxC Coupling is a professional-grade wrot copper reducing coupling engineered for high-pressure HVACR and plumbing applications. Designed for seamless copper-to-copper (CxC) connections, this fitting allows for a clean transition between 3/8” and 1/4” OD tubing, maintaining system integrity without restricted flow. Manufactured to meet rigorous ASME B16.22 and ASTM B280 standards, this Streamline series fitting provides superior thermal conductivity and natural corrosion resistance essential for refrigerant lines and pressurized supply systems. Its precision-machined solder cups ensure a consistent capillary action during the brazing or soldering process, resulting in leak-proof joints that withstand the vibration and thermal cycling common in commercial condenser and evaporator coils. For technicians focusing on refrigerant piping installation, the W01011 offers the structural reliability needed for long-term containment of modern high-pressure refrigerants in tight-tolerance mechanical environments.

Key Benefits

• Precision Tolerance: Engineered for a perfect CxC connection, ensuring optimal solder flow and a high-strength joint.
• Industrial Standards: Complies with ASME B16.22 and NSF/ANSI 61, making it suitable for both potable water and HVACR systems.
• Wrot Copper Construction: Provides excellent heat transfer and durability compared to cast alternatives, vital for refrigerant line sets.
• Corrosion Resistance: Naturally resistant to de-zincification and atmospheric corrosion in demanding mechanical rooms.

Common Questions

• Is this coupling rated for high-pressure refrigerants like R-410A? Yes, when installed with proper brazing techniques, these wrot copper fittings meet the pressure requirements of modern HVAC systems.
• Does this fitting require specific flux for installation? For HVACR applications, silver-bearing solder or brazing rods are typically used; always follow industry best practices for cleaning and fluxing copper joints.
• Can this be used for both soft and hard-drawn copper? Absolutely, it is compatible with all standard ASTM B88 and ASTM B280 copper tubing.
