Mueller W40102 2-1/8" Tee

The Mueller W40102 2-1/8" Tee is a high-grade wrot copper fitting engineered for high-capacity HVACR systems and commercial plumbing. Designed for solder-joint manual brazing, this CxCxC copper tee provides a reliable branch connection in 2-inch nominal (2-1/8" OD) piping networks. Manufactured from UNS C12200 copper, the W40102 meets ASME B16.22 and ASTM B75 standards, ensuring consistent wall thickness and metallurgical integrity for refrigeration line sets and potable water applications.

This Streamline copper tee is UL Recognized to a pressure rating of 700 PSI at 250°F, making it suitable for modern high-pressure refrigerants and demanding mechanical systems. The precision-machined cups facilitate optimal capillary action during the brazing process, resulting in leak-proof joints that withstand thermal expansion and system vibration. As a lead-free component meeting NSF 61G requirements, it is fully compliant for use in above-ground potable water supply systems.

• High-Pressure Performance: UL Recognized up to 700 PSI, ideal for R-410A and other high-pressure HVACR applications.
• Precision Engineering: Manufactured to ASME B16.22 specifications for perfect fitment with 2-1/8" OD hard-drawn copper tubing.
• Superior Material Integrity: Constructed from 99.9% pure wrot copper (C12200) for maximum corrosion resistance and thermal conductivity.
• Code Compliance: Meets NSF 61G and ASTM B75 standards for both mechanical and potable water installations.
• Contractor Trusted: Part of the Mueller Streamline series, the industry benchmark for commercial refrigeration fittings.

Is the Mueller W40102 suitable for R-410A refrigeration systems?
Yes. This fitting is UL Recognized for operating pressures up to 700 PSI, which exceeds the typical requirements for R-410A HVACR liquid and suction lines.

What is the difference between nominal 2" and 2-1/8" OD sizes?
In the HVACR industry, fittings are measured by Actual Outside Diameter (OD). This 2-1/8" copper tee corresponds to a 2" nominal size in plumbing applications, ensuring compatibility with standard Type L and Type M copper pipes.

Can this tee be used for medical gas applications?
While the W40102 is a high-quality wrot copper fitting, medical gas applications typically require "Cleaned and Bagged" (Oxy-Cleaned) versions that meet NFPA 99 standards. Verify specific project submittals before use in oxygen-enriched environments.
