Mueller W03034 Elbow

The Mueller W03034 is a professional-grade 45-degree copper elbow designed for high-performance HVACR and potable water systems. Built as a 7/8" OD (3/4" ID) wrot copper fitting, this component provides a reliable sweat connection (C x C) for seamless directional changes in piping. Engineered from high-purity UNS C12200 copper, it meets the rigorous ASTM B75 and ASME B16.22 standards, ensuring structural integrity under high-pressure conditions up to 700 PSI. The precision-machined female solder sockets are designed for optimal capillary action, allowing for consistent, leak-proof joints when properly flow-soldered. This lead-free fitting is rated for temperatures up to 250°F, making it a staple for refrigeration cycles, air conditioning liquid lines, and heating systems where flow resistance must be minimized.

• Optimal Flow Dynamics: The 45-degree angle reduces friction loss and pressure drop compared to standard 90-degree bends.
• Extreme Durability: Wrot copper construction provides superior strength-to-weight ratio and corrosion resistance for long-term service.
• Versatile Application: Suitable for ACR, refrigeration, and potable water systems requiring NSF 61G compliance.
• Global Standards: Manufactured to satisfy ASME B16.22 and MSS SP-104 specifications for industrial reliability.

• What is the difference between 7/8" OD and 3/4" ID? In HVACR, fittings are typically sized by the Outside Diameter (7/8"), whereas plumbing often refers to the Nominal/Inside Diameter (3/4"). This elbow fits both descriptions.
• Can this be used for R-410A systems? Yes, with a pressure rating of 700 PSI, it is fully compatible with modern high-pressure refrigerants.
• Is this fitting compatible with hard or soft copper? Transitioning with this fitting is seamless for both Type L and Type K hard-drawn or annealed (soft) copper tubing.
