Mueller W02072 2-1/8 90 Elbow

For high-capacity HVACR and industrial piping, the Mueller W02072 2-1/8 90 Elbow offers the mechanical integrity required for heavy-duty suction and liquid line applications. Engineered from high-grade wrot copper fitting (UNS C12200), this long radius 90 degree elbow minimizes pressure drop and turbulence, ensuring optimal flow velocity in large-diameter refrigerant circuits. This 2-1/8 inch copper elbow features precision-machined C x C sweat connections, providing a consistent capillary gap for reliable brazing with Sil-Fos or comparable alloys. Designed to withstand demanding environments, it maintains a 700 PSI pressure rating at standard operating temperatures, making it a staple for commercial ACR systems, VRF layouts, and large-scale potable water infrastructure.

Key Benefits:

• Optimized Flow Dynamics: The long radius design reduces friction loss and refrigerant flashing compared to standard short-radius elbows.
• Extreme Durability: Forged from seamless wrot copper to meet ASME B16.22 and NSF 61G standards for high-pressure reliability.
• Contractor Grade: Uniform wall thickness and precise socket depths ensure quick, leak-free joints during field installation.
• Broad Compatibility: Suitable for use with R-410A, R-22, and other high-pressure refrigerants in commercial HVACR service.

Common Questions:

What is the difference between a long radius and a short radius 2-1/8 elbow?
A long radius (LR) elbow like the W02072 has a larger centerline radius, which significantly reduces the pressure drop and internal turbulence within the system. This is critical for maintaining efficiency in long line sets or high-velocity suction lines.

Can the Mueller W02072 be used for both refrigeration and potable water?
Yes, this fitting is manufactured to meet NSF 61G lead-free requirements and ASME standards, making it suitable for both pressurized HVACR lines and above-ground potable water supply systems.

What type of solder or brazing rod is recommended?
For HVACR applications, professional technicians typically use a high-silver content brazing alloy (such as 15% silver) to ensure the joint can handle the vibration and thermal expansion common in 2-1/8" OD lines.
