1-1/4 Inch x 3/4 Inch Copper Press Reducing Coupling – Transition Fitting for Potable Water Systems

The 1-1/4 inch x 3/4 inch Copper Press Reducing Coupling is engineered for use in commercial and residential plumbing systems requiring size reduction between Type K, L, or M copper tubing. This press-fit component provides a secure, flame-free connection and is ideal for applications where efficiency, code compliance, and reliability are priorities.

Material and Functional Specifications

Manufactured from high-grade, lead-free copper, this coupling supports transition between 1-1/4 inch and 3/4 inch pipe sizes while maintaining mechanical integrity under operating pressures and thermal cycling conditions.

• ✅ Material: ASTM B75/B88 copper, lead-free alloy
• ✅ Connection Method: Press (V-profile or compatible press tool systems)
• ✅ Operating Pressure: Rated up to 200 PSI (dependent on system design and pipe support)
• ✅ Temperature Range: Suitable for continuous service from 0°F to 250°F

System Integration

Designed for use in hot and cold water distribution systems, hydronic heating loops, and approved low-pressure process piping. This press coupling eliminates the need for flame, flux, or solder, making it ideal for enclosed or occupied spaces where open flame is prohibited or impractical.

Installation Guidance

Ensure pipe ends are properly cleaned, deburred, and marked to insertion depth. Use calibrated pressing tools approved by the fitting manufacturer. Press the joint in accordance with installation guidelines and verify visual indicators to confirm correct seating and alignment.

• ✅ Reduced Installation Time: Press connections typically reduce labor by up to 60% versus soldered fittings.
• ✅ Consistent Joint Integrity: Uniform pressing ensures repeatable sealing performance.
• ✅ Code Compliance: Meets applicable ANSI, NSF, and UPC standards for potable water systems.

Application Areas

This reducing press coupling is suitable for use in branch reductions, system retrofits, and new construction where differing line sizes must be joined. It is commonly installed in riser connections, mechanical rooms, or lateral piping transitions.

Regulatory Information

Certified to NSF/ANSI 61 and NSF/ANSI 372 standards for lead-free plumbing components. Meets current national and state code requirements for use in potable water systems and is compatible with third-party press tools and calibration equipment.
