Mueller W04000 3/8" Tee

The Mueller W04000 3/8" Tee is a professional-grade wrot copper fitting engineered for high-pressure HVACR and plumbing applications. This solder joint tee features a 3/8 x 3/8 x 3/8 configuration with CxCxC connections (Copper Cup), ensuring a seamless 3-way branch for liquid or vapor lines. Manufactured from high-purity UNS C12200 grade copper, the W04000 provides superior thermal conductivity and inherent antimicrobial properties, making it a staple for both potable water systems and pressurized refrigerant loops. Built to meet stringent ASME B16.22 and MSS SP104 standards, this 3/8-inch copper fitting is rated for operating pressures up to 700 PSI at 250°F. Its seamless construction allows for reliable field brazing or soldering, providing the mechanical strength needed to withstand vibration and thermal expansion in commercial mechanical systems. As a veteran-choice refrigeration copper tee, it ensures tight tolerances for a precise fit with ASTM B88 or ASTM B280 tubing.

• Precision Engineered: Manufactured to ASME B16.22 specifications for consistent wall thickness and fitment across all 3/8" OD inlets.
• High Pressure Performance: Tested and validated for 700 PSI, making it suitable for modern high-pressure refrigerant cycles.
• Maximum Durability: Constructed from wrot copper (ASTM B75/B88) for enhanced corrosion resistance and joint integrity.
• Industry Versatility: Fully compliant with NSF/ANSI 61G for use in safe drinking water and above-ground pressurized systems.

Is the Mueller W04000 compatible with R-410A systems?
Yes, when used with appropriate brazing alloys, these wrot copper fittings meet the pressure requirements for R-410A refrigeration and AC applications.

What is the difference between 1/4" nominal and 3/8" OD for this tee?
In the HVACR industry, this part is frequently identified by its 3/8" Outside Diameter (OD), which corresponds to 1/4" nominal plumbing size. Always verify your tubing OD before soldering.

Can this tee be used for medical gas installations?
The W04000 is manufactured by Mueller Streamline, and while the material meets high standards, always ensure specific de-greasing and cleaning protocols are followed per local codes for medical gas service.
