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

1/2 Inch PEX Copper Insert Adapter – Female Crimp x PEX

The 1/2 inch PEX copper insert adapter (Female Crimp) is a transition fitting used to connect copper pipe or threaded fittings to PEX tubing in potable water distribution and hydronic systems. One end features a female NPT thread, and the other provides a PEX insert leg compatible with ASTM F1807 or F2159 crimp or clamp connection methods.

Material and Construction

• ✅ Lead-Free Copper Alloy – Manufactured to meet NSF/ANSI 61 and 372 standards for potable water systems.
• ✅ Corrosion-Resistant Build – Engineered for resistance to dezincification and long-term mechanical reliability.
• ✅ Precision Threads – Female NPT end conforms to ANSI B1.20.1, ensuring secure sealing with compatible male-threaded fittings or valves.

System Compatibility and Standards

This fitting is designed for use in hot and cold potable water lines and heating systems where transition between PEX tubing and threaded copper or brass components is required. It is compatible with:

• ✅ PEX Tubing: ASTM F876/F877 compliant
• ✅ Crimp Rings/Clamps: ASTM F1807 (brass crimp) and F2159 (poly-alloy crimp)
• ✅ Standards: NSF 14, NSF 61, NSF 372; IPC and UPC approved

Installation Requirements

Join the PEX end using a properly sized crimp ring or stainless steel clamp ring and a compatible crimping or cinch tool. Apply thread sealant or PTFE tape to the female threads for sealing to male NPT pipe or fittings. Always verify alignment and torque specifications during assembly to ensure joint integrity and compliance with plumbing code requirements.

Application Uses

Commonly installed in residential and commercial systems to terminate or adapt water supply lines, branch runs, fixture supplies, or mechanical connections requiring female threaded outlets. Ideal for use in rough-in or retrofit applications where threaded copper-to-PEX transitions are required.

Technical Summary

• Nominal Size: 1/2 inch
• End 1: Female NPT
• End 2: PEX Insert (crimp or clamp compatible)
• Material: Lead-Free Brass or Copper Alloy (DZR)
• Pressure Rating: Up to 200 psi (varies by system design)

Code Note

This fitting is certified for use in potable water systems and meets federal lead-free requirements under the Safe Drinking Water Act. Approved for installation in jurisdictions using IPC, UPC, or CPC standards.
