1 inch PEX Brass Insert Adapter Crimp x Male Copper Sweat

1-Inch PEX Brass Insert Adapter – Crimp x Male Sweat Transition Fitting

This 1-inch brass transition adapter is designed for joining PEX tubing to copper tubing systems, offering a dependable solution where crimp and sweat connections are required in one fitting. Engineered for permanent, pressure-rated connections, this fitting meets the mechanical demands of both residential and commercial plumbing installations.

It features a PEX insert end for ASTM F1807/F877 compliant crimp connections and a male sweat end for direct soldering into copper fittings or valves. Its lead-free brass composition meets current potable water code requirements.

Application Advantages

• ✅ Dual-Use Configuration – Designed for direct PEX-to-copper transitions in mixed-material systems.
• ✅ Lead-Free Brass Body – Certified to NSF/ANSI 372 standards for potable water systems.
• ✅ Mechanical Strength – Withstands typical system pressures and thermal expansion cycles.

Installation Overview

The crimp side is compatible with copper crimp rings or stainless steel clamp systems when installed using ASTM-compliant tools. The male sweat end requires proper cleaning, fluxing, and torch soldering to ensure a uniform and secure seal within copper fittings.

Ensure temperature control and pressure testing are performed post-installation in accordance with local plumbing code procedures. Proper alignment and insertion depth are essential for maintaining joint integrity over the system’s life span.

Common Field Applications

This fitting is typically used in retrofit projects, distribution manifolds, or service loopouts where copper supply lines interface with PEX distribution. It is suitable for both pressurized potable systems and closed-loop heating where appropriate.
