The 247Garden 4-Pack 1-inch PEX-B x 1-inch Female Sweat Copper 90-Degree Elbow is the perfect solution for creating reliable 90-degree transitions between 1-inch PEX-B tubing and 1-inch copper pipe. Designed for both potable water and hydronic heating applications, these fittings are manufactured from lead-free, dezincification-resistant (DZR) brass to ensure strength, corrosion resistance, and long-term durability.

Each elbow is tested and certified to NSF, UPC, and CSA standards and meets ASTM F1807 requirements. With a performance rating of up to 200°F and 200 psi, these fittings deliver consistent results in demanding plumbing systems. The female sweat x PEX barb design makes installation straightforward while providing a watertight and secure transition between copper and PEX lines.

Compatible with both stainless steel clamp rings and copper crimp rings (sold separately), this 4-pack gives you flexibility, value, and convenience. Plus, free shipping anywhere in the USA is included.

Installation Instructions – Step by Step

Tools & Materials Needed:

• PEX tubing cutter

• Copper tubing cutter

• Emery cloth or wire brush

• Torch, flux, and lead-free solder

• PEX crimp tool or clamp tool

• Copper crimp rings or stainless steel clamp rings

• Go/No-Go gauge

Step 1: Prepare the Copper Pipe

Cut the copper pipe square, clean the surface with emery cloth, and apply flux.

Step 2: Sweat the Copper Connection

Insert the pipe into the female sweat end, heat evenly, apply solder, and let cool naturally.

Step 3: Prepare the PEX Tubing

Cut the tubing square using a PEX cutter, then slide a copper crimp or stainless steel clamp ring over it.

Step 4: Connect the PEX Tubing

Insert tubing fully onto the barb, position the ring 1/8"–1/4" from the end.

Step 5: Secure the Connection

• Crimp rings: Use a calibrated crimp tool, then check with a Go/No-Go gauge.

• Clamp rings: Tighten securely using a clamp tool.

Step 6: Inspect & Test

Check all joints, then pressure-test the system before covering or finishing.

Pro Tips

• Always cut PEX squarely with a PEX cutter.

• Avoid overheating the copper joint.

• Calibrate your crimp tool regularly for accuracy.

• Provide proper pipe support to reduce stress on fittings.

• Pressure test before completing installation.
