1/2 inch x 1/4 inch Copper Reducing Adapter – Engineered for Secure Pipe Size Transitions

The 1/2 inch x 1/4 inch Copper Reducing Adapter provides a seamless transition between different nominal pipe sizes within drainage, waste, and vent (DWV) or water supply systems. Manufactured to meet applicable industry standards, this fitting ensures compatibility and performance in environments where dimensional precision and material reliability are essential.

Fabricated from lead-free copper, the adapter is corrosion-resistant and thermally stable, making it suitable for potable water and mechanical system applications. Its smooth interior surface minimizes turbulence and supports consistent flow performance even under varying pressure conditions.

Product Features

• ✅ Material: C12200 copper – seamless wrought construction for superior mechanical strength.
• ✅ Connection Type: Cup x Cup (sweat solder) configuration designed for brazed or soldered connections.
• ✅ Pressure Rating: Suitable for systems up to 200 psi when properly installed with soldered joints.
• ✅ Temperature Range: Up to 400°F for soldered connections under continuous service conditions.
• ✅ Compliance: Conforms to ASME B16.22 and NSF/ANSI 61/372 for potable water applications.

Applications

This copper reducing adapter is commonly used in domestic and commercial plumbing systems where a transition from 1/2 inch to 1/4 inch pipe is required. Applications include water supply distribution, chilled water loops, air conditioning lines, or low-pressure process systems. The fitting’s precision tolerances facilitate secure connections and reduce the potential for joint failures over time.

Installation Guidelines

Install using standard copper soldering methods in accordance with ASTM B828. Clean all mating surfaces with an appropriate brush or abrasive cloth, apply flux evenly, and use lead-free solder compatible with potable water systems. Heat should be applied uniformly to ensure a strong metallurgical bond.

Note on Code Requirements

Lead-free copper fittings are mandated by the Safe Drinking Water Act (SDWA) and are a requirement under UPC and IPC standards across all jurisdictions in the United States. This adapter is certified for compliance with these regulations, making it suitable for both new construction and retrofit projects.

The 1/2 inch x 1/4 inch Copper Reducing Adapter is an essential component for maintaining pressure integrity and dimensional compatibility when downsizing copper piping. Its robust design and compliance with national standards make it a reliable solution for code-approved plumbing assemblies.
