Mueller W01028 3/4" Coupling

The Mueller W01028 3/4" Coupling is a professional-grade wrot copper fitting engineered for high-pressure HVACR and plumbing applications. Manufactured from 99.9% pure UNS C12200 copper, this CxC (Copper-to-Copper) coupling features a rolled stop to ensure precise tube positioning and consistent solder flow during installation. Designed to meet ASME B16.22 and ASTM B75 standards, the W01028 is rated for operating pressures up to 700 PSI at 250°F, making it suitable for both refrigeration lines and potable water systems. Its lead-free construction complies with NSF 61G, providing long-term reliability in specialized mechanical environments. For contractors requiring sweat fittings that maintain structural integrity under thermal expansion, this 3/4 inch copper coupling provides the industrial durability needed for multi-zone hydronic or commercial refrigerant piping.

Key Benefits

• High-Pressure Performance: Rated for 700 PSI, ideal for modern high-pressure refrigerants and HVACR service.
• Precision Alignment: Integrated rolled stop prevents over-insertion and ensures a solid solder joint.
• Material Grade: Constructed from wrot copper (UNS C12200) for superior corrosion resistance and thermal conductivity.
• Compliance Certified: Meets ASME B16.22, ASTM B75, and NSF 61G standards for broad system compatibility.

Common Questions

• Is this coupling compatible with R-410A refrigeration systems? Yes, its 700 PSI rating at 250°F makes it highly suitable for high-pressure refrigeration and air conditioning applications.
• Can the Mueller W01028 be used for potable water? Absolutely. It is manufactured from lead-free wrot copper and meets NSF/ANSI 61 requirements for drinking water.
• Does this fitting require specific soldering techniques? It uses standard sweat connection methods; ensure the 3/4" OD tube is cleaned and fluxed properly before reaching the rolled stop.
