1/2 inch x 1/8 inch Copper Reducing Coupling Copper x Copper

1/2 inch x 1/8 inch Copper Reducing Coupling – Sweat x Sweat

The 1/2 inch x 1/8 inch Copper Reducing Coupling is designed for soldered connections between copper tubing of dissimilar diameters. Commonly used in water distribution and hydronic heating systems, this coupling provides a smooth reduction in pipe size while maintaining structural and flow integrity within soldered assemblies.

Technical and Material Properties

• ✅ Material: Wrot copper, lead-free and NSF/ANSI 61/372 compliant
• ✅ End Connections: Socket x Socket (sweat ends)
• ✅ Nominal Sizes: 1/2 inch inlet x 1/8 inch outlet
• ✅ Manufacturing Standard: Compliant with ASME B16.22 and applicable ASTM standards

Performance Features

• ✅ Uniform Wall Thickness: Maintains pressure integrity and ensures even heat distribution during soldering
• ✅ Precision Machining: Designed to meet tight tolerances for accurate tube insertion and solder retention
• ✅ Corrosion Resistance: Suitable for both hot and cold potable water lines, as well as low-pressure hydronic systems
• ✅ Flow Efficiency: Internal reduction provides a gradual transition to minimize turbulence and maintain flow velocity

Installation Notes

Installation requires proper pipe preparation including reaming, cleaning, and flux application. Soldering must be completed using lead-free solder and a heat source compatible with copper fitting work. Always verify insertion depth and alignment prior to applying heat. Not intended for press or mechanical connections.

Use Cases

This reducing coupling is commonly used in:

• Potable water distribution lines requiring downsizing at fixture branches
• Hydronic heating systems involving transitions between main and terminal piping
• Mechanical rooms and retrofit installations where dimensional constraints require compact reduction

Code Compliance

Lead-free copper fittings such as this are mandated for potable water systems under U.S. federal plumbing regulations and meet local code requirements when installed per standard practice.

The 1/2 inch x 1/8 inch Copper Reducing Coupling supports efficient layout transitions and system performance consistency. Its precision-formed design and reliable material composition make it a preferred solution for high-integrity copper piping installations.
