Mueller Industries W02734 Elbow

The Mueller Industries W02734 is a professional-grade 7/8" OD x 7/8" OD C x C sweat fitting designed for high-demand HVAC and refrigeration applications. Engineered as a 90-degree long radius elbow, this wrot copper component provides a gradual sweep that significantly reduces turbulent airflow and pressure drop compared to standard short-radius elbows. Built to ASME B16.22 and ASTM B75 specifications, the Mueller W02734 supports a 700 PSI pressure rating at temperatures up to 250°F, making it suitable for high-pressure refrigerants like R-410A. Its long radius copper elbow design ensures maximum flow efficiency in suction and discharge lines. For veteran technicians, the precision-machined solder-joint copper fitting ends offer consistent capillary action for reliable, leak-free brazing. This HVAC 90 degree elbow is NSF 61G certified for potable water and meets all standard copper refrigeration fitting requirements for above-ground installations, ensuring long-term system integrity in residential and commercial split systems.

• High Flow Efficiency: The long radius sweep reduces friction loss and internal turbulence in refrigerant lines.
• Precision Machining: Wrot copper construction ensures the 7/8 inch OD ends have tight tolerances for superior solder-joint integrity.
• R-410A Compatible: Rated for 700 PSI, this fitting handles the high operating pressures of modern HVACR systems.
• Industry Standards: Meets ASME B16.22 and NSF 61G for use in both refrigeration and potable water supply.

What is the difference between a long radius and short radius elbow?
A long radius elbow like the Mueller W02734 has a larger centerline radius, which helps maintain higher velocity and lower pressure drop across the fitting, critical for efficient oil return in refrigeration systems.

Is the Mueller W02734 compatible with ACR tubing?
Yes, this fitting is specifically designed to accept 7/8" OD ACR copper tubing. The 3/4" nominal identification is common in plumbing, but for HVACR applications, the 7/8" OD sweat connection is the technical standard.

Can this fitting be used in high-temp discharge lines?
Absolutely. The wrot copper material is rated for continuous operation up to 250°F, making it a reliable choice for the hottest parts of the refrigeration cycle.
