Mueller W02082 2-5/8 x 2-5/8 Copper CxC 90 Elbow

The Mueller W02082 2-5/8 x 2-5/8 Copper CxC 90 Elbow is a heavy-duty wrot copper fitting engineered for light commercial and industrial HVACR refrigeration systems. Built to withstand the rigorous demands of pressurized lines, this long radius 90-degree elbow is designed with a sweep that significantly reduces pressure drop and turbulence—critical for maintaining system efficiency in high-capacity air conditioning and refrigeration applications. Its CxC (Copper-to-Copper) connection ensures a secure, leak-free solder joint when properly brazed, conforming to ASME B16.22 and NSF 61G standards for material purity and performance.

This fitting is manufactured from high-grade UNS C12200 wrot copper, providing superior thermal conductivity and corrosion resistance. With a 2-1/2 inch nominal size (2-5/8" OD), it is ideal for ACR tubing runs where smooth flow transitions are required to prevent oil trapping and excessive vibration. Veteran technicians choose the Streamline brand for its dimensional consistency, ensuring a tight fit and reliable capillary action during the brazing process.

Key Benefits

• High Flash Point Compatibility: Engineered for use in both suction and liquid lines within pressurized HVACR systems.
• Reduced Pressure Loss: The long-radius design minimizes frictional resistance, optimizing compressor performance and energy output.
• Professional Durability: Constructed from 99.9% pure wrot copper, meeting ASTM B75 requirements for structural integrity.
• Industry Standard Compliance: UL recognized and certified to ASME B16.22, ensuring compatibility with standard HVACR piping layouts.

Common Questions

• What is the difference between this and a short-radius elbow? The long-radius (LR) sweep provides approximately 1.5 times the pipe diameter in curvature, which lowers pressure drop compared to the tighter turn of a short-radius fitting.
• Can this be used for R-410A systems? Yes, provided the wall thickness of the accompanying copper tubing meets the requisite pressure ratings for the refrigerant used.
• Does this fitting require specific brazing alloys? It is compatible with standard BCuP and BAg series brazing fillers commonly used in the trade.
