Mueller W04068 1-3/8" Tee

The Mueller W04068 1-3/8" Tee is a professional-grade wrot copper fitting engineered for high-pressure HVACR applications and pressurized plumbing systems. As a veteran in the field, you know that clean, precise solder joints are critical for system integrity; this CxCxC copper tee is manufactured to ASME B16.22 standards, ensuring consistent wall thickness and optimal tolerances for 1-1/4" nominal (1-3/8" OD) tubing. Constructed from high-purity UNS C12200 grade copper, this fitting is UL recognized to 700 psi, making it a reliable choice for modern high-pressure refrigerants like R-410A. Its lead-free composition meets NSF 61G requirements, allowing for seamless integration into potable water supply systems without compromising safety. Whether you are manifolding a commercial refrigeration rack or piping a heavy-duty hydronic loop, the Streamline W04068 provides the structural durability and thermal conductivity required to maintain long-term performance in demanding mechanical environments.

• Engineered for High-Pressure: UL recognized to 700 psi at 250°F, ideal for rigorous refrigeration service.
• Precision Tolerance: Manufactured to ASME B16.22 specifications for reliable, leak-free solder joint connections.
• Superior Material Quality: Made from 99.9% pure wrot copper (UNS C12200) for excellent corrosion resistance.
• Multi-Use Versatility: Dual-certified for both HVACR and potable water systems under NSF 61G.

What is the difference between nominal size and OD for this tee?
In the HVACR trade, this is a 1-3/8" OD fitting. For plumbing applications, it is referred to as a 1-1/4" nominal tee. Both refer to the same Mueller W04068 part designed for 1-3/8" outside diameter copper tubing.

Can this fitting be used with R-410A refrigeration systems?
Yes, this wrot copper pressure fitting is designed to handle the high operating pressures of R-410A, provided the brazing or soldering is performed according to industry standard practices for high-pressure mechanical systems.

Is the Mueller W04068 suitable for underground installation?
Yes, wrot copper fittings like the Streamline W04068 are approved for both above-ground and underground pressurized water and mechanical systems when properly installed and protected against soil-specific corrosion.
