Mueller W03063 2-5/8 x 2-5/8 Copper CxC 45 Elbow

Technicians working on high-capacity commercial refrigeration or VRF systems know that the Mueller W03063 2-5/8 x 2-5/8 Copper CxC 45 Elbow is the industry standard for maintaining flow efficiency in large-diameter lines. This wrot copper 45-degree elbow is engineered from high-purity UNS C12200 copper alloy, ensuring a dense, non-porous structure that handles high-pressure refrigerants without risk of seepage. Measuring 2-5/8" OD (2-1/2" nominal), these ACR copper fittings feature precision-machined solder joint connections that facilitate deep solder penetration for a leak-proof seal. Built to meet ASME B16.22 and MSS SP104 standards, this fitting is UL Recognized for operating pressures up to 700 PSI at 250°F, making it suitable for modern high-pressure R-410A systems and CO2 subcritical applications. Its 45-degree configuration offers a significant reduction in pressure drop compared to standard 90-degree bends, which is critical for maintaining compressor efficiency and system longevity in industrial HVACR environments.

• Flow Dynamics: The 45-degree radius reduces turbulence and pressure loss, optimizing the performance of high-velocity suction and discharge lines.
• Material Integrity: Constructed from 99.9% pure wrot copper to provide superior thermal conductivity and corrosion resistance.
• High-Pressure Rating: Third-party verified to withstand up to 700 PSI, ensuring reliability in demanding commercial refrigeration cycles.
• Standard Compliance: Manufactured to meet strict ASTM B280 and ASME B16.22 specifications for HVACR piping.

Is this fitting compatible with hard-drawn and soft copper tubing?
Yes, the C x C (Cup to Cup) ends are designed to join ASTM B280 and ASTM B88 seamless copper tube. For the 2-5/8" OD size, it is typically used with hard-drawn Type K or L ACR tubing.

Can this 45-degree elbow be used in medical gas applications?
While wrot copper is inherently suitable, medical gas installations require fittings that are specifically cleaned, bagged, and capped to meet NFPA 99 standards. Verify if your specific job site requirements allow for field cleaning or necessitate factory-prepped ACR/MED fittings.

What is the difference between nominal and OD sizing for this part?
In the HVACR trade, this is a 2-5/8" OD fitting. In plumbing applications, it may be referred to by its 2-1/2" nominal size. Always confirm by the outside diameter (OD) when selecting refrigeration components.
