Tools and Materials You’ll Need

Before you begin, make sure you have the necessary tools and materials:

1. PEX tubing
2. PEX press connectors
3. PEX press tool (compatible with the connector size)
4. Pipe cutter or PEX tubing cutter
5. Deburring tool
6. Go/no-go gauge (for checking crimp quality)
7. Safety glasses
8. Gloves
9. Marker
10. Measuring tape

Step 1: Measure and Cut

Measure the length of PEX tubing you need for your installation and mark it with a marker. Use a pipe cutter or PEX tubing cutter to make a clean, perpendicular cut at the marked location.

Step 2: Deburr the Edges

After cutting, use a deburring tool to remove any burrs or sharp edges from the cut end of the PEX tubing. This ensures a smooth connection with the press fitting.

Step 3: Inspect the Press Fitting

Before making the connection, inspect the PEX press connector for any visible damage or defects. It’s essential to use a fitting in good condition to ensure a reliable connection.

Step 4: Insert the Press Connector

Slide the PEX press connector onto the cut end of the PEX tubing. Make sure it goes in smoothly and seats securely against the tubing stop.

Step 5: Use the PEX Press Tool

Select the appropriate-sized PEX press tool for the connector you’re using. Place the jaws of the press tool over the press fitting. Make sure the tool is perpendicular to the fitting.

Step 6: Press the Connection

Squeeze the press tool handles together with a firm, even force. The tool will compress the PEX tubing and connector, creating a watertight seal. Most press tools have a built-in indicator or “click” sound to signal when the connection is complete.

Step 7: Check the Connection

After pressing, use a go/no-go gauge to check the quality of the connection. The gauge should slide smoothly over the pressed area. If it doesn’t, the connection may be faulty and should be redone.

Step 8: Repeat as Needed

Repeat these steps for all the PEX press connectors you need to install in your plumbing system.

Conclusion

PEX press connectors offer a reliable and efficient way to join PEX tubing, making them a preferred choice for many plumbing professionals. By following this step-by-step guide and ensuring proper tool selection and technique, you can confidently install PEX press connectors for your plumbing project, providing secure and leak-free connections. Always follow manufacturer guidelines and local plumbing codes for a safe and successful installation.
