Mueller W03030 3/4 x 3/4 Copper CxC 45 Elbow

As a seasoned tech, you know the reliability of Mueller Streamline is the benchmark for copper pressure fittings. The Mueller W03030 is a 3/4" x 3/4" (5/8" nominal) 45-degree wrot copper elbow engineered for high-performance HVACR and potable water systems. Manufactured from 99.9% pure UNS C12200 grade copper, this solder-joint fitting provides superior flow dynamics and thermal conductivity, essential for maintaining system efficiency in refrigeration and hydronic heating applications.

This 45-degree CxC (Cup x Cup) fitting is built to handle 700 PSI at temperatures up to 250°F, making it a rugged choice for R410A refrigeration lines and high-pressure steam. Its precision-engineered solder cups facilitate consistent capillary action, ensuring leak-free joints under mechanical stress. Compliant with ASME B16.22 and NSF 61G lead-free standards, the W03030 integrates seamlessly into commercial and residential piping layouts where tight directional changes and low friction loss are critical for the compressor's longevity and overall fluid velocity.

• Engineered for HVACR: Rated for 700 PSI, ideal for high-pressure refrigerants and pressurized water systems.
• Industrial-Grade Material: Constructed from UNS C12200 wrot copper for maximum corrosion resistance and durability.
• Precision Solder Cups: Designed for optimal fit and flow-control, ensuring professional-grade sweat connections every time.
• Full Standard Compliance: Meets ASME B16.22, B16.50, and NSF/ANSI 61 requirements for safety and performance.
• Superior Flow Dynamics: The 45-degree bend reduces pressure drop compared to 90-degree elbows, improving system COP.

What is the difference between 3/4" OD and 5/8" nominal for this fitting?
In the HVACR trade, this fitting is often referred to by its 3/4" Outside Diameter (OD), which corresponds to the 5/8" nominal size used in standard plumbing. It is designed to fit 3/4" OD ACR tubing or 5/8" nominal K/L/M copper pipe.

Can this fitting be used in suction lines for air conditioning?
Yes, the W03030 is commonly used in both liquid and suction lines. Its wrot copper construction and 700 PSI rating make it suitable for various refrigerant gases, including R-22 and R-410A.

Is this elbow compatible with lead-free solder?
Absolutely. These fittings are manufactured to meet NSF 61G requirements and are fully compatible with modern lead-free soldering alloys and bridging techniques required by current codes.
