1 inch x 1/2 inch Copper Reducing Coupling – For DWV and Potable Water Systems

The 1 inch x 1/2 inch Copper Reducing Coupling is engineered to join copper tubing of dissimilar diameters in both pressure and drainage applications. Designed for precision soldered connections, this fitting supports smooth system transitions while maintaining code compliance and long-term reliability in service lines and distribution networks.

Professional-Grade Features

• Manufacturing Standard: Complies with ASME B16.22 and ASTM B75/B88 for wrought copper fittings.
• Connection Type: Sweat (cup x cup) ends for seamless soldering with type K, L, or M copper tube.
• Material Composition: Lead-free wrought copper, meeting the Safe Drinking Water Act requirements.
• Dimensional Fit: Precisely machined to ensure correct wall alignment and axial fit during installation.
• Corrosion Resistance: Suitable for potable water, hydronic heating, and DWV systems.

Installation and Compatibility

This coupling is designed for soldered installation and requires proper cleaning, flux application, and heating to form a solid joint. Its reduced-end configuration allows for a direct connection between 1 inch and 1/2 inch copper tubing, minimizing the need for additional transitions. The fitting is compatible with both vertical and horizontal lines and can be used in above-ground or in-wall assemblies.

Application Areas

Ideal for residential and commercial systems where copper tubing diameters need to be transitioned. Commonly used in water supply lines, HVAC loops, and branch line connections requiring compact, corrosion-resistant fittings with a clean appearance.

Field Note

Reducing couplings offer a more efficient flow transition than using separate bushings and couplings, reducing the number of solder joints and potential leak points.
