How to Make PEX Pipe Connections How to Make PEX Pipe Connections

What You'll Need
PEX pipe
Tubing cutter
PEX crimping tool
Copper fitting
Copper crimp ring
PEX crimp gauge

PEX pipe (or crosslinked polyurethane) is a type of water pipe that is easier to use than copper, iron or PVC. It is flexible and does not need as many fittings. Connecting PEX pipe is not difficult, and this easy to follow how-to guide will walk through the process. Let's get started.

Step 1 - Cut the Pipe

Use a tubing cutter to cut the pipe. Slide the cutter onto the pipe and twist the cutter around the pipe in a rotating motion to make the cut.

Step 2 - Install Crimp Ring

Slide the copper crimp ring about 1/4 to 1/2 inch from the edge of the pipe at the point where you made the cut. Do the same for the other piece of PEX pipe you will be connecting.

Step 3 - Insert Fitting

Insert the copper fitting into the ends of the two pieces of PEX pipe you will be joining.

Step 4 - Crimp Connection

To seal the connection, place the crimper tool onto the crimp ring. Then, squeeze the handle of the crimper tool together until the ring depresses and seals the connection. Do the same for the other ring on the other piece of PEX pipe.

Step 5 - Test Connection

To test the crimped connection, slide the PEX crimp gauge over the crimp ring. If the crimp is okay, the ring will slide perfectly into the "GO" slot on the gauge. If there is a problem with the connection, it will fit into one of  the "NOGO" slots and will need to be redone.
