3/4 inch PEX Brass Insert Adapter Crimp x Copper Female Sweat

3/4 inch PEX Adapter – Crimp x Female Sweat for Cross-Material Transitions

The 3/4 inch PEX Adapter Crimp x Copper Female Sweat is designed to provide a secure transition between PEX tubing and copper systems. Fabricated from lead-free brass and engineered to meet dimensional and pressure performance standards, this fitting enables reliable joint integrity in potable water and hydronic applications.

It features a PEX crimp connection on one end and a female sweat (socket) on the other, allowing for easy integration between different piping materials. The adapter is compliant with low-lead plumbing codes and intended for use in systems requiring long-term mechanical and corrosion resistance.

Product Advantages for Contractors

This fitting is suited for residential and commercial installations that demand both code compliance and time-efficient assembly:

• ✅ Lead-Free Brass Body Certified for potable water use and compliant with NSF/ANSI 61 and 372 standards.
• ✅ PEX Crimp End Compatible with ASTM F1807 crimp systems using copper rings for secure attachment to PEX tubing.
• ✅ Female Sweat Socket Accepts nominal copper pipe, allowing for soldered connections to existing copper infrastructure.
• ✅ Durable Machining Precision-formed threads and socket depths support uniform sealing performance across installations.
• ✅ Mixed-Material Applications Ideal for transitions in hybrid plumbing systems or retrofit projects requiring cross-material compatibility.
