1-1/4" x 1-1/4" x 1" Copper Press Reducing Tee – Press-Fit Tee for Potable Water and Hydronic Systems

The 1-1/4" x 1-1/4" x 1" copper press reducing tee provides a reliable method for branching and reducing copper tube within press-connect systems. Designed for use in potable water distribution, heating, and chilled water applications, this fitting accommodates a reduction in outlet diameter while maintaining structural integrity and pressure performance.

Constructed from lead-free wrought copper, the press connections utilize sealing elements compressed with specialized press tools to create permanent, leak-resistant joints without the need for soldering or open flames. The fitting conforms to current codes and certifications for use in both residential and commercial systems.

Specifications

• Material: Lead-free wrought copper (ASTM B75/B88)
• Size: 1-1/4" x 1-1/4" x 1"
• Connection Type: Press (all three outlets)
• Seal Element: EPDM or HNBR, depending on application rating
• Pressure Rating: Up to 200 PSI, depending on system and seal type
• Certifications: NSF/ANSI 61 and 372, ICC-ES PMG, CUPC listed, Lead-Free compliant

Features and Benefits

• ✅ Press Connection Design – Eliminates the need for heat or solder, reducing installation time and increasing jobsite safety
• ✅ System Reduction – Tee configuration enables downsizing of one branch line for fixture or zone-specific flow control
• ✅ Lead-Free Compliance – Meets Safe Drinking Water Act standards for use in potable water systems nationwide
• ✅ High-Strength Copper Body – Resistant to thermal expansion and mechanical vibration in pressurized systems

Installation Requirements

Proper installation requires the use of an approved press tool with compatible jaws. Ensure tube ends are deburred, clean, and fully inserted to marked depth before activating the press. Refer to the manufacturer's installation instructions for proper alignment and pressing procedures. No solder, flux, or adhesive is used in this connection method.

Typical Applications

This press reducing tee is suitable for hot and cold potable water systems, closed-loop hydronic heating, chilled water distribution, and other mechanical piping applications where reliable branch connections and diameter transitions are needed. It may be installed in both exposed and concealed locations where access to soldering is limited or restricted by code.

Material Note

Wrought copper press fittings provide a clean, fire-safe solution for copper systems in both retrofit and new construction. The integrated sealing element is rated for standard system temperatures and should be verified for chemical compatibility in specialty applications.

The 1-1/4" x 1-1/4" x 1" copper press reducing tee is engineered to support code-compliant construction and long-term system performance in high-demand building environments.
