1/2 inch PEX Brass Insert Adapter Crimp x Copper Female Sweat

1/2" PEX Crimp x Female Copper Sweat Adapter – Brass Transition Fitting

The 1/2" Crimp x Copper Female Sweat Adapter is engineered to provide a secure and code-compliant transition between PEX tubing and copper piping systems. This fitting features a PEX crimp connection on one end and a female sweat (cup) end on the other, allowing for a smooth and efficient transition between dissimilar piping materials in potable water applications.

Key Features and Benefits

• ✅ Lead-Free Brass Construction: Manufactured from dezincification-resistant, lead-free brass (DZR) compliant with ASTM F1807 and NSF/ANSI 61 & 372 for potable water use.
• ✅ PEX Compatibility: The barbed crimp end is compatible with ASTM F1807 PEX systems and accepts standard copper crimp rings or stainless steel clamp rings (ASTM F877).
• ✅ Copper Integration: Female sweat connection fits standard copper tube sizes (CTS) and is designed for soft soldering per ASTM B813 and B32.
• ✅ Reliable Sealing: Tight tolerances reduce the likelihood of leaks and support long-term system integrity under working pressures up to 160 psi at 73°F (based on system rating).
• ✅ Corrosion-Resistant Material: Brass body resists corrosion and stress cracking, suitable for demanding job site conditions.

Installation Considerations

Use approved PEX crimp tools to secure the barbed end and a torch with lead-free solder for the copper connection. Always follow local plumbing codes and manufacturer guidelines when installing transition fittings. Deburr and clean copper tubing before soldering, and pressure test the system after installation.

Common Applications

Suitable for potable water distribution systems in residential and light commercial construction. Often used when retrofitting or modifying existing systems that require transitions between copper and PEX tubing in kitchens, bathrooms, or mechanical rooms.

Code Compliance Note

This fitting complies with federal lead-free legislation (Reduction of Lead in Drinking Water Act) and is approved for use in all jurisdictions that mandate low-lead content in potable systems.

The 1/2" PEX Crimp x Female Sweat Adapter is a reliable solution for contractors seeking durable, compliant connections between copper and PEX systems. Built to meet rigorous industry standards, this fitting ensures both performance and safety across a wide range of installation scenarios.
