3/4 inch x 1/2 inch Copper Reducing Coupling Copper x Copper

3/4" x 1/2" Copper Reducing Coupling – Built for System Efficiency

The 3/4" x 1/2" Copper Reducing Coupling is designed to provide a consistent and secure transition between pipe sizes in potable water systems. Fabricated from lead-free copper and engineered to meet ANSI/NSF standards, this coupling supports sweat connections for dependable, code-compliant installations across a range of residential and light commercial applications.

Performance Highlights

• ✅ Lead-Free Copper – Suitable for use in drinking water systems; complies with NSF/ANSI 61 and 372 requirements.
• ✅ Uniform Wall Thickness – Maintains structural integrity and supports proper heat transfer during soldering.
• ✅ Precision Sweat Fit – Manufactured to tight dimensional tolerances for streamlined joint assembly and reduced solder volume.
• ✅ Corrosion-Resistant – Durable copper resists scaling and internal buildup, supporting long service life in various water conditions.

Installation Considerations

Intended for soldered copper systems, this fitting requires standard cleaning and flux preparation. A torch and lead-free solder are used to establish the joint. Ensure pipe ends are properly deburred and cleaned to allow for smooth insertion and optimal bonding. This fitting is designed for use with type L and M copper tubing.

Typical Applications

Used to join 3/4" and 1/2" copper pipes in branch line or main-to-appliance transitions. Common in new construction, retrofits, and maintenance applications involving potable water, chilled water, or hydronic heating systems.
