Mueller W01072 2-1/8" Coupling

The Mueller W01072 is a high-performance 2-1/8" OD copper coupling engineered for professional HVACR and pressurized plumbing applications. This wrot copper fitting features a rolled stop (WC-400), ensuring precise tube alignment and consistent solder flow during installation. Manufactured from UNS C12200 grade copper to meet ASTM B75 and ASME B16.22 standards, it provides the structural integrity required for critical refrigeration cycles and potable water systems. This CxC connection (Cup x Cup) is rated for 700 PSI at 250°F, making it a reliable choice for high-pressure R-410A systems. The seamless construction minimizes potential leak points, while the nitrogen-compatible material prevents internal oxidation during brazing. Contractors depend on this Streamline series coupling for its dimensional accuracy and NSF/ANSI 61G lead-free compliance, facilitating a clean, industrial-grade joint that holds up under thermal expansion and vibration in commercial environments.

• Engineered for High-Pressure: UL recognized for 700 PSI, ideal for modern HVACR refrigerants and high-head pressure systems.
• Precision Rolled Stop: Feature WC-400 rolled stop to simplify tube positioning and ensure a uniform solder ring.
• Superior Material Quality: Constructed from wrot copper meeting ASTM B75 specifications for maximum corrosion resistance and durability.
• Industry Standard Compliance: Fully compliant with ASME B16.22 and NSF 61G for both mechanical and potable water applications.
• Clean Brazing: Compatible with nitrogen-purged environments to maintain system 100% cleanliness and performance.

What is the difference between nominal size and OD for this part?
In the trade, this is often called a 2" nominal fitting, but for HVACR applications, it is specifically sized for 2-1/8 inch outside diameter copper tubing.

Is this coupling suitable for R-410A refrigeration lines?
Yes, the Mueller W01072 is rated for 700 PSI, which meets the operating pressure requirements for R-410A and similar high-pressure refrigerants.

Can this be used for both soldering and brazing?
Precisely. This C x C copper coupling is designed for standard solder joints or high-temperature brazing, depending on the specific system requirements and local codes.
