Mueller W01027 5/8 x 1/4 Coupling

The Mueller W01027 is a trade-grade 5/8 x 1/4 Copper CxC Coupling engineered for professional HVACR and plumbing applications. This precision-machined reducing coupling is constructed from high-purity wrot copper (UNS C12200), ensuring superior thermal conductivity and corrosion resistance in pressurized systems. Designed for a seamless copper to copper (CxC) solder joint, it facilitates a reliable transition between different tubing diameters without sacrificing line integrity. With a pressure rating of up to 700 PSI and a maximum operating temperature of 250°F, this Mueller Streamline fitting is ideal for refrigeration systems, above-ground potable water lines, and residential heating circuits. Every HVAC copper fitting from this series meets rigorous ASME B16.22 standards, providing technicians with the tight tolerances required for leak-proof performance. Whether you are performing a line set repair or a new system install, this copper pipe reducer delivers the mechanical strength and metallurgical consistency needed for demanding field environments.

• Superior Material Integrity: Manufactured from 99.9% pure wrot copper for maximum durability in high-pressure HVACR environments.
• Precision Dimensions: Features 5/8 inch x 1/4 inch outside diameter (OD) sizing for exact fitment with ACR and plumbing tubing.
• System Compatibility: Rated for 700 PSI, making it suitable for modern high-pressure refrigerants and fluid transfer applications.
• Solder Ready: Clean, burr-free ends ensure optimal capillary action during the brazing or soldering process.
• Standard Compliance: Meets ASME B16.22 and NSF 61G specifications for use in both mechanical and potable water systems.

Common Questions

Can this coupling be used with R-410A systems?
Yes, the Mueller W01027 is rated for 700 PSI, which exceeds the typical operating pressures of R-410A systems, provided proper brazing techniques are used.

Is this fitting compatible with both hard and soft copper tubing?
This copper CxC coupling is designed to work with all standard Type K, L, and M copper tubing, as well as ACR-rated hard and soft tempered tube.

Does this reducer include an internal pipe stop?
Yes, most Streamline reducing couplings feature a built-in stop to ensure the tubing is inserted to the correct depth for a secure, uniform joint.
