When you are fitting PEX tubing into an older house, then you may need some PEX connectors to attach your new plastic pipe to the older metal ones. Most older homes use copper, iron or galvanized metal for their pipework, and this can mean that you need a specialist fitting to attach them. You will also need to use PEX connectors when making a pipe-to-pipe fitting on your PEX layout.

Step 1  - Attach the Ring

Lay out your pipe, and then cut down the exposed edge. Take the PEX connectors, and slide one into the hole. Place the PEX connection ring over the top of this.

Step 2 - Secure the Fitting

Once the PEX fitting is tightly in place, you will then need to secure the fitting, or seal it in order to make it completely watertight. Put the crimping tool around the ring of your PEX connector, and then squeeze. You will need to press tightly to secure the ring.

Step 3 - Using a Push Fitting

There are a number of different types of PEX fitting, which need to be installed differently. For a Push-installation type of PEX connectors, you will need to trim the ends of your pipe, and then simply push the pipe into the push fitting. This will secure it.
