Mueller W04031 7/8" Tee

The Mueller W04031 7/8" Tee is a professional-grade wrot copper fitting engineered for high-performance fluid handling in HVACR systems and potable water applications. This 7/8 x 7/8 x 7/8 CxCxC Tee is manufactured from UNS C12200 copper, ensuring superior corrosion resistance and optimal thermal conductivity. Designed to meet ASME B16.22 and ASTM B75 standards, this fitting supports a 700 PSI pressure rating at temperatures up to 250°F, making it a reliable solution for liquid, suction, and discharge lines. The precision-machined solder-joint connections ensure a tight, leak-proof seal when used with standard brazing alloys or soft solders. As a staple for any service truck, the Streamline WT-600 series provides the structural integrity required for commercial refrigeration and industrial piping where lead-free copper fittings are mandatory for NSF 61G compliance. Field-proven and built to last, the W04031 handles the vibration and thermal expansion stresses common in condenser and evaporator coil manifold assemblies.

• Maximum System Integrity: Manufactured to ASME B16.22 specifications for consistent wall thickness and fit-up.
• Versatile Compatibility: Ideal for R410A refrigeration systems, potable water supply, and hydronic heating loops.
• High Pressure Tolerance: Rated for a 700 PSI working pressure, providing a significant safety margin for modern high-pressure refrigerants.
• Clean Installation: Precision-formed copper-to-copper connections ensure uniform capillary flow during the brazing process.
• Regulatory Compliance: Meets NSF/ANSI 61 and 372 requirements for lead-free potable water service.

Is this fitting compatible with R410A lines?
Yes, the Mueller W04031 is rated for the high-pressure demands of R410A and other common HVACR refrigerants, provided the brazing material and installation follow industry standards.

Can I use this tee for ACR applications?
Absolutely. While often listed as 3/4" nominal in plumbing, this 7/8" OD tee is the standard size for refrigeration linesets and ACR-grade copper tubing.

Does this meet lead-free requirements for drinking water?
Yes, this wrot copper tee is 100% lead-free and complies with NSF 61G, making it safe for all potable water infrastructure.
