1/2 inch PEX Copper Insert Adapter PEX x Press

1/2" PEX x 1/2" Copper Adapter – Lead-Free Transition Fitting for Potable Water Systems

This 1/2" PEX x 1/2" Copper Adapter is a transition fitting designed to connect cross-linked polyethylene (PEX) tubing to copper piping in potable water distribution systems. Manufactured from lead-free materials in compliance with NSF/ANSI 372, it ensures safe use in drinking water applications while meeting local and national plumbing codes.

Engineered for use in both residential and commercial installations, the adapter supports pressure-rated systems that require compatibility between modern polymer tubing and traditional metallic piping. It is commonly used during retrofits, system upgrades, or hybrid piping assemblies where dissimilar materials must be joined with mechanical reliability.

Fitting Characteristics

• ✅ Lead-Free Certification – Compliant with the Safe Drinking Water Act and NSF/ANSI 61 and 372 standards for potable systems.
• ✅ Material Compatibility – Enables direct transition between 1/2" PEX tubing and 1/2" nominal copper pipe.
• ✅ Pressure Rated – Suitable for hot and cold water systems operating up to typical residential pressure limits (e.g., 160 PSI at 73°F).
• ✅ Mechanical Stability – Designed to reduce joint failure due to thermal expansion and contraction or mechanical stress at material transition points.
• ✅ Code Compliant – Approved for use in installations governed by UPC, IPC, and local code jurisdictions requiring lead-free components.

Technical Specifications

• Nominal Size: 1/2" PEX x 1/2" Copper
• Material: Lead-free brass or copper alloy (varies by model)
• Connection Type: PEX crimp/barb or expansion x sweat (verify variant)
• Certification: NSF/ANSI 61 and 372 compliant
• Operating Pressure: Up to 160 PSI @ 73°F (verify with manufacturer for exact rating)

Installation Guidelines

Install the PEX connection using an approved crimp, clamp, or expansion tool as required by the fitting type and tubing standard (ASTM F1807, F1960, or F2159). The copper side should be soldered using standard practices with lead-free solder and flux suitable for potable applications. All installations must comply with applicable plumbing codes, including pressure testing prior to system commissioning.

Application Use

Commonly installed in domestic water systems requiring connection between existing copper risers and new PEX distribution lines. Typical use cases include bathroom remodels, kitchen retrofits, mechanical room tie-ins, and system repiping projects.

Note on Compliance

Use of lead-free transition fittings is mandated by U.S. federal law for any system supplying water intended for human consumption. This fitting meets all current regulatory and certification standards for safe material use in potable applications.
