Mueller W01022 5/8" Coupling

The Mueller W01022 is a high-grade 5/8" Copper CxC Coupling engineered for professional HVACR and plumbing applications where a permanent, leak-proof joint is critical. This wrot copper fitting features a rolled stop (WC-400), which ensures positive tube positioning by preventing over-insertion during the brazing or soldering process. Fabricated from UNS C12200 alloy, the coupling provides superior corrosion resistance and thermal conductivity, essential for maintaining system integrity in high-pressure environments. With a 700 PSI pressure rating at 250°F, it is a staple for copper pipe repair and new installations. This lead-free copper coupling meets rigorous industry standards, including ASME B16.22 and NSF 61G, making it suitable for both potable water supply and refrigerant lines. Contractors rely on the Streamline brand for consistent wall thickness and tight tolerances that simplify field assembly. Whether you are extending 5/8 inch copper tubing or performing a mid-run repair, this coupling delivers the professional reliability required for commercial infrastructure.

• Rolled Stop Design: Integrated center stop ensures precise tube alignment and prevents sliding past the joint center.
• High Pressure Performance: Rated for up to 700 PSI at 250°F, making it ideal for demanding refrigeration and HVAC cycles.
• Lead-Free Certification: Fully compliant with NSF 61G standards for safe use in potable water systems.
• Precision Wrot Copper: Manufactured from ASTM B75 C12200 copper for maximum durability and effortless soldering.
• Broad Compatibility: Standardized dimensions allow for seamless integration with all 5/8" OD copper tubing.

Is this coupling suitable for ACR (refrigeration) applications?
Yes, the 5/8" size and high pressure/temperature ratings make it a reliable choice for liquid and suction lines in HVACR systems.

Does this fitting require brazing, or is soft soldering sufficient?
This wrot copper coupling is designed for sweat connection and can be either soft-soldered for plumbing or brazed for high-pressure refrigeration applications.

What standards does the Mueller W01022 meet?
It is manufactured to meet ASME B16.22, MSS SP-104, and is UL listed, ensuring it handles the mechanical stresses of professional installations.
