Mueller W04001 1/2" Tee

The Mueller W04001 1/2" Tee is a professional-grade wrot copper fitting engineered for permanent, leak-proof connections in high-pressure HVACR and plumbing systems. This 1/2 x 1/2 x 1/2 CxCxC copper tee features three female solder cups designed to accept 1/2" nominal tubing (5/8" OD), providing a reliable branch point for fluid or refrigerant distribution. Manufactured from high-purity C12200 alloy, this Streamline series fitting is optimized for sweat-joint installation, ensuring superior capillary action and joint integrity during the brazing or soldering process.

Designed for demanding environments, the Mueller W04001 maintains a robust pressure rating of up to 700 PSI and a temperature threshold of 250°F, making it a staple for R-410A refrigerant lines, potable water supply, and hydronic heating loops. This fitting meets ASME B16.22 and NSF/ANSI 61 standards, guaranteeing compliance for both residential and commercial mechanical projects. The precision-machined stops within each cup facilitate accurate tube depth seating, reducing turbulence and preventing flow restrictions across the copper-to-copper connection.

Key Benefits for Technicians:

• Superior Material Integrity: Constructed from seamless wrot copper to eliminate porosity and ensure long-term corrosion resistance in pressurized systems.
• Broad Fluid Compatibility: Suitable for a wide range of applications including refrigeration, air conditioning, and liquid line branching.
• Industry Compliance: Manufactured to meet ASTM B75 and ASME B16.22 specifications for dimensional accuracy and structural strength.
• Uniform Heat Transfer: High thermal conductivity allows for consistent heating during the soldering process, ensuring deep penetration of the filler metal.

Common Questions:

What is the actual outside diameter (OD) of the tubes this tee accepts?
This is a 1/2" nominal fitting, which is designed to fit over 1/2" nominal copper tubing. The actual outside diameter of that tubing (and the internal diameter of the tee's cups) is 5/8".

Can this tee be used for R-410A high-pressure refrigerant lines?
Yes, as a wrot copper fitting rated for approximately 700 PSI at standard operating temperatures, it is compatible with R-410A and other common HVACR refrigerants when installed using proper brazing techniques.

Is this fitting lead-free for potable water use?
Yes, Mueller wrot copper fittings are made from 99.9% pure copper and meet NSF 61 requirements for use in potable water systems.
