Mueller W03050 Elbow

When you're running 1-3/8" OD lines, the Mueller W03050 45 degree elbow is the industry standard for maintaining flow velocity and minimizing pressure drop in high-capacity refrigeration and HVAC systems. Built from high-grade wrot copper (UNS C12200), this CxC (Cup x Cup) fitting is engineered for maximum reliability in pressurized environments. Unlike standard plumbing elbows, this Streamline series fitting is UL Recognized for operating pressures up to 700 psi at 250°F, making it fully compatible with high-pressure refrigerants like R-410A. It conforms to strict ASME B16.22 and ASTM B75 standards, ensuring consistent wall thickness and internal diameters for a perfect solder joint every time. Whether you are navigating tight mechanical rooms or installing large-scale VRF systems, this 1-3/8 copper elbow provides the structural integrity needed for above-ground potable water and HVACR applications.

• Precision Tolerance: Manufactured to ASME B16.22 specifications for reliable, leak-free solder connections.
• High Pressure Rating: Tested and UL Recognized to handle 700 psi, ideal for modern HVACR systems.
• Pure Wrot Copper: Constructed from 99.9% pure wrot copper for superior thermal conductivity and corrosion resistance.
• Optimized Flow: The 45-degree bend reduces turbulence compared to 90-degree turns, preserving system efficiency.
• Lead-Free Certified: Meets NSF/ANSI 61 standards, safe for potable water supply systems.

Is the Mueller W03050 compatible with R-410A refrigeration systems?
Yes, its 700 psi rating makes it a staple for high-pressure refrigeration lines where standard plumbing fittings would fail.

What is the exact outside diameter (OD) for this fitting?
This is a 1-3/8 inch OD 45-degree elbow, typically used with 1-1/4 inch nominal copper tubing (Type L or M).

Can this fitting be used in medical gas applications?
While built to the same ASTM B75 material standards, ensure your specific project requires "Cleaned and Bagged" (Oxy/Med) certification before use in medical gas systems.
