Mueller W01049 1-1/8 x 7/8 Coupling

The Mueller W01049 is a premium wrot copper reducing coupling designed for high-performance HVACR and plumbing applications. This 1-1/8 x 7/8 CxC coupling facilitates a seamless transition between different copper tube diameters, ensuring optimal flow dynamics in refrigeration systems and potable water lines. Engineered to meet ASME B16.22 and ASTM B75 standards, this solder joint fitting is manufactured from high-grade C12200 alloy, providing the structural integrity required for pressurized environments. With a 700 PSI pressure rating at temperatures up to 250°F, it is a reliable choice for ACR copper pipe installations involving R-410A and other high-pressure refrigerants. The WC-400R series design incorporates a centered stop to ensure precise tube seating every time. As a veteran-preferred streamline copper fitting, the W01049 offers the tight tolerances and material consistency necessary for leak-free brazing in the field.

• Precision Tolerance: Manufactured to ASME B16.22 specifications for consistent cup-to-tube fitment, reducing the risk of brazing failures.
• High-Pressure Ready: Rated for up to 700 PSI, making it ideal for modern HVACR systems and high-pressure liquid lines.
• Material Purity: Forged from Wrot Copper C12200, ensuring excellent thermal conductivity and corrosion resistance in potable water systems.
• Universal Compatibility: Designed for use with Type K, L, and M copper tubing in residential, commercial, and industrial settings.
• Compliance Certified: Meets NSF/ANSI 61G lead-free requirements and is UL recognized for safety and performance.

• Is this coupling suitable for brazing or just soldering? This wrot copper fitting is designed for both brazing and soldering. For high-pressure refrigeration applications, brazing with a high-silver content alloy is recommended.
• What are the actual dimensions for HVACR vs. Plumbing? In HVACR terms, this is a 1-1/8" OD x 7/8" OD coupling. For plumbing applications, this corresponds to 1" ID x 3/4" ID nominal sizing.
• Can this be used for underground installations? While primarily used in above-ground supply systems, it can be used underground if installed and protected according to local mechanical codes and ASME guidelines.
