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 (for sweating copper)

• PEX crimp tool or clamp tool

• Copper crimp rings or stainless steel clamp rings (sold separately)

• Go/No-Go gauge for crimp verification

Step 1: Prepare the Copper Pipe

1. Cut copper pipe square using a tubing cutter.

2. Clean the end thoroughly with emery cloth or wire brush.

3. Apply a thin, even layer of flux.

Step 2: Sweat the Copper Connection

1. Insert the copper pipe into the female sweat end of the elbow.

2. Heat evenly with a torch until flux sizzles.

3. Apply lead-free solder and let it flow into the joint.

4. Allow the joint to cool naturally.

Step 3: Prepare the PEX Tubing

1. Cut PEX tubing squarely.

2. Slide a crimp ring or clamp ring over the tubing.

Step 4: Connect the PEX Tubing

1. Insert tubing fully onto the PEX barb.

2. Position the crimp or clamp ring 1/8"–1/4" from the tubing end.

Step 5: Secure the Connection

• Copper Crimp Rings: Use a calibrated crimp tool and verify with Go/No-Go gauge.

• Stainless Steel Clamp Rings: Use a clamp tool until fully secured.

Step 6: Inspect & Test

1. Ensure all connections are secure.

2. Pressure-test before covering pipes or closing walls.

3. Confirm there are no leaks under operating conditions.

Pro Tips for Successful Installation

• Use a proper PEX cutter for clean, square cuts.

• Avoid overheating copper joints.

• Calibrate crimp tools before installation.

• Support PEX lines to reduce stress on fittings.

• Always perform a pressure test before finalizing installation.
