Mueller W01017 1/2" Coupling

The Mueller W01017 1/2" Coupling is a critical component for technicians requiring a secure, permanent connection in pressurized systems. Engineered from wrot copper (UNS C12200), this CxC solder-joint fitting includes a precision-engineered rolled stop to ensure positive tube positioning and efficient capillary flow during the brazing or soldering process. Specifically designed for HVACR applications and potable water systems, it meets strict ASTM B16.22 and ASME B16.50 standards, providing a reliable 700 PSI pressure rating at 250°F. Whether you are performing a field repair or a full system install, the 1/2" OD copper coupling delivers the structural integrity needed for above-ground and underground industrial piping. Its lead-free NSF 61G certification makes it suitable for residential plumbing, while its thermal conductivity and corrosion resistance satisfy the rigorous demands of commercial refrigeration cycles. Rely on this American-made copper fitting for a leak-proof interface that maintains system performance under high-pressure conditions.

• Rolled Stop Design: Integrated center stop ensures the copper tubing is seated at the correct depth for a uniform solder joint.
• High-Pressure Capability: Validated for operating pressures up to 700 PSI, making it ideal for high-pressure refrigerant lines.
• Industrial Compliance: Manufactured to meet ASTM B75 and ASME B16.22 specifications for dimensional accuracy and material purity.
• Versatile Application: Certified for use in HVAC, refrigeration, and potable water systems with NSF 61G lead-free compliance.
• Corrosion Resistance: High-grade wrot copper construction provides long-term durability against oxidation and chemical degradation.

What is the difference between a rolled stop and a dimpled stop?
A rolled stop like the one on the Mueller W01017 provides a continuous internal ridge that prevents the tube from over-inserting, ensuring an even distribution of solder, whereas dimpled stops use small protrusions that may offer less structural support during high-heat brazing.

Is the Mueller W01017 compatible with R-410A systems?
Yes, this 1/2 inch copper coupling is rated for the high pressures associated with R-410A and other modern refrigerants, provided the solder or brazing alloy used is also rated for those specific conditions.

Can this fitting be used for underground installations?
While primarily used for above-ground piping, wrot copper fittings are suitable for underground applications when installed according to local mechanical codes and properly protected against soil acidity.
