1/2 inch PEX Brass Insert Adapter PEX x Copper

1/2" PEX x 1/2" Copper Lead-Free Adapter – Engineered for Cross-Material Transitions

The 1/2" PEX x 1/2" Copper Lead-Free Adapter is designed to enable direct transitions between PEX tubing and nominal copper pipe in potable water systems. Manufactured from forged lead-free brass, this fitting ensures compliance with federal low-lead regulations and provides long-term reliability in high-demand plumbing environments.

This adapter supports ASTM F1807 and F877 systems when using crimp or clamp connections on the PEX side and standard sweat or press fittings on the copper end. It’s pressure-rated for up to 200 psi at 200°F, suitable for residential and light commercial distribution lines requiring material interface without compromising structural integrity.

Key Features

• ✅ Lead-Free Brass Construction – Fully compliant with NSF/ANSI 61 and 372 standards for potable water use.
• ✅ Secure Transition – Connects PEX (ASTM F876/F877) to copper pipe in accordance with code-mandated installation practices.
• ✅ High Temperature & Pressure Ratings – Suitable for continuous use at elevated temperatures and pressures common in domestic supply lines.
• ✅ Corrosion Resistant – Brass composition resists dezincification and pitting over time, even in aggressive water conditions.
• ✅ Mechanical Integrity – Precision-machined barbs ensure full engagement and sealing surface retention on PEX tubing when properly crimped or clamped.

Installation Requirements

This fitting requires the use of a compatible ASTM F1807 crimp ring or stainless steel clamp and tool for the PEX side. The copper side is typically soldered or pressed depending on system design. Proper deburring and adherence to local code guidelines for joint preparation is essential to prevent leaks and ensure joint longevity.

Typical Applications

Used extensively in new construction and retrofit applications where PEX is interfaced with copper risers, manifold outlets, or branch circuits. Ideal for potable water lines, hydronic heating, and system repairs where lead-free compliance and code-approved connections are required.
