1/2 in. PEX-B x 3/4 in. Female Sweat Copper Pipe Adapter (Lead Free DZR Brass NSF F1807 PEX Crimp Fitting)

The 247Garden 1/2 in. PEX-B x 3/4 in. Female Sweat Copper Pipe Adapter is a professional-grade plumbing fitting designed for secure, reliable transitions from copper tubing to PEX-B piping. Constructed from lead-free, DeZincification Resistant (DZR) brass, this fitting meets ASTM F1807 standards and is NSF certified, providing a durable, safe, and leak-resistant connection for potable water and hydronic heating systems.

Key Features and Benefits:

• Compatibility: Designed for use with all PEX-B pipe/tubing and standard copper tubing.

• Durable Construction: Lead-free DZR brass ensures long-term corrosion resistance and strength.

• PEX Crimp System: Works with PEX-B crimp rings and compatible crimp tools (sold separately). Not compatible with cold-expansion systems.

• Certified and Safe: NSF certified for potable water; compliant with ASTM F1807, UPC, IPC, and cUPC standards.

• Temperature and Pressure Ratings: Suitable for typical residential and commercial hot and cold water applications.

Tips & Tricks – Step-by-Step Installation:

Step 1: Prepare the Copper Pipe

• Cut the copper pipe squarely and remove any burrs with a deburring tool.

• Clean the outside of the copper pipe and the inside of the female brass fitting using a wire brush or emery cloth for optimal solder adhesion.

Step 2: Apply Flux

• Apply a thin, even layer of lead-free flux to both the copper pipe and the fitting. Flux ensures proper flow of solder and prevents oxidation during heating.

Step 3: Solder the Copper Connection

• Heat the fitting evenly with a propane torch until the flux begins to bubble.

• Touch lead-free solder to the joint; it should flow by capillary action around the pipe to create a leak-proof seal.

• Let the joint cool naturally before proceeding.

Step 4: Prepare the PEX-B Pipe

• Slide a PEX crimp ring over the end of the PEX-B pipe.

• Insert the pipe fully onto the fitting barb.

Step 5: Crimp the PEX-B Connection

• Use a compatible PEX crimp tool to secure the crimp ring, ensuring a tight, leak-free seal.

• Verify the crimp with a go/no-go gauge if available.

Applications:
Ideal for potable water systems, hydronic heating systems, and any plumbing project requiring a secure, durable transition from copper to PEX-B piping.
