3/4 in. PEX-A Expansion x 1/2 in. Male Sweat Copper Adapter NSF Lead Free Brass ASTM F1960 Cold Expansion PEX Fitting

The 247Garden 3/4 in. PEX-A Expansion x 1/2 in. Male Sweat Copper Adapter is a premium plumbing fitting engineered for reliable, long-lasting transitions between PEX-A tubing and copper piping in potable water and hydronic heating systems. This adapter allows you to first sweat the 1/2 inch male copper end into a female copper fitting, then connect 3/4 inch PEX-A tubing via cold-expansion, ensuring a secure, leak-free connection on both sides.

Premium Construction and Performance:

• Made from lead-free, dezincification-resistant (DZR) brass for maximum durability and corrosion resistance.

• Certified to NSF standards and compliant with ASTM F1960, making it suitable for potable water systems.

• Designed for full-flow performance, maintaining optimal water delivery across the transition from PEX-A to copper.

Installation Guide & Tips:

1. Copper Connection (Sweat First):

   • Clean and flux the copper pipe and the male sweat adapter end.

   • Insert the male sweat end into the female copper fitting.

   • Sweat the connection using proper soldering techniques to ensure a reliable, leak-proof joint.

   • Allow the joint to cool completely before handling.

2. PEX-A Connection (Cold Expansion):

   • Slide a 3/4 inch expansion ring onto PEX-A tubing (sold separately).

   • Use the appropriate expander tool (sold separately) to expand the tubing over the barbed fitting.

   • Allow the tubing to contract fully for a permanent, secure, leak-free seal.

3. Tips & Tricks:

   • Only compatible with PEX-A tubing and expansion rings; do not use with PEX-B, PEX-C, crimp, or clamp systems.

   • Ensure tubing is cut square and burr-free for smooth expansion.

   • Use the included protection cap to prevent debris from entering the fitting during storage.

   • Confirm full contraction of the PEX tubing before pressurizing the system.

Key Features and Benefits:

• Seamless PEX-to-Copper Transition: Sweat the copper first, then connect PEX-A tubing via expansion for secure, leak-free connections.

• Premium Materials: Lead-free DZR brass ensures long-lasting performance and safe potable water use.

• Standards Compliant: ASTM F1960 and NSF certified for professional-grade reliability.

• Full-Flow Design: Maintains maximum water flow across both PEX and copper connections.

• Versatile Applications: Suitable for potable water, hydronic heating, radiant floor heating, and other plumbing projects.
