Mueller Industries W02716 Elbow

The Mueller Industries W02716 is a professional-grade 3/8" OD x 3/8" OD copper 90-degree elbow engineered for high-performance HVACR and plumbing applications. This long radius copper elbow features a sweat CxC (Copper x Copper) connection, designed to provide a reduced pressure drop compared to standard short-radius fittings. Manufactured from high-purity, seamless copper tubing, it meets ASTM B88 and ASME B16.22 standards, ensuring structural integrity in both potable water systems and refrigeration lines. Its corrosion-resistant properties make it an industry standard for aboveground water-supply systems and HVAC piping where maintaining laminar flow is critical. For technicians, the W02716 offers consistent wall thickness and tight tolerances for reliable brazing or soldering, resulting in leak-free joints under high-vibration conditions common in condensing units and evaporator coils.

Key Technician Benefits

• Optimized Flow Dynamics: The long radius design minimizes turbulence and frictional resistance, improving overall system efficiency.
• Precision Tolerance: Precision-engineered sweat sockets ensure consistent capillary action during soldering for a secure seal.
• Dehydrated and Sealed: Suitable for refrigeration (ACR) applications requiring clean, moisture-free internal surfaces.
• Technical Compliance: Built to withstand the thermal expansion and contraction cycles typical in commercial HVACR installs.

Common Contractor Questions

What is the difference between Nominal and OD sizing for this part?
In the HVACR trade, this is a 3/8" OD elbow. In standard plumbing terminology, it is referred to as 1/4" nominal. Always verify your tube diameter before brazing.

Can this fitting be used in high-pressure R-410A systems?
Yes, when installed with proper brazing techniques (such as using sil-fos), these wrought copper fittings are rated for the high pressures required in modern refrigerant piping.

Is this elbow compatible with soft copper tubing?
Absolutely. The W02716 90-degree elbow is designed to interface with both hard-drawn and annealed (soft) copper tubing conforming to ASTM specifications.
