1/2″ Copper Adapter – Lead-Free Fitting for Potable Water Transitions

The 1/2″ Copper Adapter is a transition fitting designed for use in potable water distribution systems, providing a secure interface between threaded and soldered copper connections. Manufactured from lead-free copper alloy in accordance with current regulatory standards, this fitting meets NSF/ANSI 61 and 372 requirements for drinking water system components.

Suitable for both new construction and retrofit plumbing projects, the adapter allows for consistent installation where dissimilar joining methods are required—such as copper tube to threaded brass or galvanized pipe. It is engineered to maintain structural integrity under temperature and pressure ranges defined for Type L and M copper piping systems.

Technical Attributes

• ✅ Lead-Free Compliance – Fabricated to meet Safe Drinking Water Act standards under NSF/ANSI 372.
• ✅ Machined Threads – NPT threads manufactured to ANSI B1.20.1 for reliable sealing with compatible fittings and valves.
• ✅ Corrosion Resistance – Copper construction provides long-term resistance to scale, pitting, and chemical degradation in potable water systems.
• ✅ Solder Joint Compatibility – Designed for joining with solder or brazed copper connections using standard Type L or M tubing.
• ✅ System Versatility – Commonly used in domestic water supply risers, fixture connections, and valve assemblies.

Specification Data

• Material: Lead-free copper alloy
• Nominal Size: 1/2 inch
• Connection: Male or female NPT x solder cup (depending on variant)
• Certifications: NSF/ANSI 61 and 372; compliant with UPC, IPC
• Operating Pressure: Suitable for standard residential and commercial potable water systems

Installation Notes

Install using standard copper soldering practices for the socket end. Apply thread sealant or PTFE tape to the threaded side as required by system design. Threads should be engaged to manufacturer-recommended torque specifications to avoid over-tightening or deformation. Always verify system pressure and temperature limits are within specification post-installation.

Typical Use Cases

Utilized in domestic water supply lines, transition points between copper and threaded pipe systems, and appliance or fixture connections. Common in both horizontal and vertical piping configurations where compact, corrosion-resistant fittings are required.

Regulatory Compliance Note

Federal law mandates the use of lead-free plumbing components in potable water systems. This adapter is certified lead-free and suitable for code-compliant installations in all jurisdictions governed by national plumbing standards.
