Mueller W03012 3/8 x 3/8 Copper CxC 45 Elbow

The Mueller W03012 is a professional-grade 3/8 x 3/8 copper 45 elbow engineered specifically for critical flow control in HVACR systems. Constructed from high-purity Wrot UNS C12200 copper, this solder-joint pressurized fitting provides the structural integrity required to handle high-pressure refrigerants and potable water. With a robust 700 PSI pressure rating at 250°F, it excels in demanding residential and commercial refrigeration environments. This CxC (Copper-to-Copper) connection ensuring a precise, leak-proof female solder-joint when used with ASTM B280 or ASTM B88 seamless copper tube. Designed to meet ASME B16.22 and MSS SP-104 standards, the W03012 offers a low-profile 45-degree directional change, minimizing turbulence and pressure drop compared to standard 90-degree bends. This lead-free copper fitting is also NSF/ANSI 61 certified, making it safe for drinking water applications while maintaining the corrosion resistance necessary for long-term mechanical reliability in the field.

• High-Pressure Performance: Specifically rated for up to 700 PSI, making it ideal for modern high-pressure refrigerant cycles.
• Precision Tolerance: Manufactured to ASME B16.22 standards for consistent 3/8-inch OD engagement and reliable capillary flow during brazing.
• Versatile Compatibility: Seamlessly integrates with Type K, L, and M copper tubing for diverse mechanical and plumbing configurations.
• Industrial Durability: Wrot copper construction provides superior thermal conductivity and resistance to dezincification in harsh environments.

What is the difference between 3/8" OD and 3/8" Nominal for this fitting?
In HVACR, this fitting is sized as 3/8" Outside Diameter (OD). If you are working on a plumbing application where "Nominal" sizing is used, this fitting would correspond to a 1/4" Nominal measurement. Always verify your tube's OD before soldering.

Can this 45-degree elbow be used for brazing instead of soft soldering?
Yes, Mueller Streamline wrot copper fittings are designed for both solder and braze joints. For high-pressure refrigeration work, brazing with a silver-bearing alloy is recommended to ensure joint strength.

Is the W03012 suitable for suction lines or liquid lines?
It is compatible with both. Its smooth internal radius is engineered to facilitate directional changes in liquid lines or suction lines while maintaining optimal flow characteristics and reducing the risk of oil trapping.
