Installation Instructions – Step by Step

Tools & Materials Needed:

• PEX tubing cutter

• Copper tubing cutter

• Emery cloth or wire brush (for cleaning copper pipe)

• Torch, flux, and lead-free solder (for sweating copper)

• PEX crimp tool or clamp tool (depending on system used)

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

• Go/No-Go gauge for crimp connections

Step 1: Prepare the Copper Pipe

1. Cut the copper pipe square using a copper tubing cutter.

2. Clean the pipe end with emery cloth or a wire brush until shiny, removing all oxidation and debris.

3. Apply a thin, even layer of flux to the outside of the copper pipe.

Step 2: Sweat the Copper Connection

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

2. Heat the joint evenly with a torch until the flux begins to sizzle.

3. Apply lead-free solder to the joint. The solder should melt and flow into the joint.

4. Allow the joint to cool naturally, without disturbing the connection.

Step 3: Prepare the PEX Tubing

1. Cut the PEX tubing squarely using a PEX cutter.

2. Slide a copper crimp ring or stainless steel clamp ring over the tubing.

Step 4: Connect the PEX Tubing to the Elbow

1. Insert the PEX tubing fully onto the PEX barb of the elbow fitting.

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

Step 5: Secure the PEX Connection

• If using Copper Crimp Rings:

  • Use a calibrated PEX crimp tool to compress the ring evenly around the tubing.

  • Verify the crimp using a Go/No-Go gauge.

• If using Stainless Steel Clamp Rings:

  • Use a clamp tool to tighten the ring until fully secured.

Step 6: Inspect & Test

1. Check all connections to ensure proper seating and secure fastening.

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

3. Confirm there are no leaks under operating conditions.

Pro Tips for a Successful Installation

• Always use a PEX tubing cutter to avoid angled or rough cuts.

• Never overheat the copper joint; excessive heat can damage the fitting or nearby components.

• When using PEX crimp rings, ensure your crimp tool is calibrated correctly before installation.

• Support your PEX lines properly to prevent unnecessary stress on fittings.

• Perform a pressure test before finalizing any installation.
