1-1/2 inch x 1 inch Copper Reducing Coupling – Wrot Copper, Lead-Free, Sweat x Sweat

The 1-1/2 inch x 1 inch Copper Reducing Coupling is manufactured from high-grade, lead-free wrought copper (UNS C12200) and is designed to transition between two nominal copper tube sizes in potable water, HVAC, or mechanical piping systems. This coupling meets the dimensional requirements of ASME B16.22 and is third-party certified for NSF/ANSI 61 and 372 compliance.

With its smooth interior surface and precision-formed ends, this coupling allows for uniform soldering, minimal flow restriction, and secure alignment during installation. It is engineered for use with Type K, L, and M hard or annealed copper tubing in above-ground and accessible concealed locations, in accordance with applicable plumbing codes.

Technical Specifications

• Size: 1-1/2 inch x 1 inch
• Material: Lead-free wrought copper (C12200)
• Connection Type: Solder (cup x cup)
• Standards: ASME B16.22, MSS SP-104, NSF/ANSI 61 & 372
• Pressure Rating: 200 PSI at 250°F when properly installed with compatible tubing

Performance Characteristics

• ✅ Corrosion Resistance – Copper’s natural resistance to scaling and rust supports long-term system integrity.
• ✅ High-Temperature Tolerance – Suitable for use in hot and cold potable water and hydronic systems.
• ✅ Reduced Friction Loss – Uniform bore and smooth interior walls promote consistent flow characteristics.
• ✅ Reliable Joint Assembly – Deep solder cups and concentric ends facilitate cleaner sweat joints with better capillary action.
• ✅ Code-Approved – Manufactured to current plumbing and mechanical code requirements.

Installation Notes

Ensure copper tube ends are clean and deburred prior to assembly. Apply flux evenly and heat uniformly to achieve proper solder flow. For optimal results, use lead-free solder compatible with potable systems. All installations should comply with local plumbing codes and be pressure-tested before system operation.

Typical Applications

This copper reducing coupling is commonly installed in water distribution systems, boiler return lines, and manifold assemblies. It is especially useful in systems requiring a compact transition between varying copper tube sizes without compromising flow efficiency or code compliance.

Regulatory Compliance

Lead-free copper fittings are mandated nationwide under the Safe Drinking Water Act. This product satisfies those requirements and is certified for use in all potable water applications.

Note for Contractors: When selecting copper fittings for pressure or temperature-critical systems, verifying material grade and compliance with applicable specifications is essential. This fitting delivers long-term performance with the assurance of code conformity and installation flexibility.
