How to Choose the Best PEX Expansion Tool?

Now that you have read the 5 top PEX expanders, you may want to know how these are selected for this buying guide. Here are the criteria that we have followed to pick the best of the best products.

1. Build Quality

The first thing we have considered to make the list is the build quality of the product. No one loves to spend hundreds of bucks on a product that is not so durable.

As we could not use the product to check where they are durable or not. We have used the experience of the real users to measure the overall build quality of the product. We considered factors like how often a product needs to be repaired, how much time before the product is useless, how much time before the first maintenance of the product is done, etc.

2. Ease of Use

The next thing to consider is the comfort when using the machine. If you are a professional, then you should not skip this criterion.

We have considered the overall design of the product, its ergonomics, and comfort when using it. Poorly designed products can make your job tiresome and can give you some serious pain when used for a long time.

3. Versatility

When we talk about versatility, we mean versatility in the sizes of the tubes. Not all expanders allow you to expand many sizes of the tubes.

Generally, mid range products come with 3 different size settings while high end products offer more. Unless you are taking the product for a project only, you should go for the most versatile option as it would save you from buying a new machine to make a bigger or smaller sized tube.

4. PEX Expander Price

When I check a product, I check its price before anything else. This is because price tells many things about the product. While there are exceptions to this, higher priced products are generally come with high configuration and endless features.

And you can’t ignore the budget too. That’s why keep your eye on the price tag also when making the decision.

5. Tool Carry Case

Some PEX expanders come with handy tool organizing and carry case while some skip it. Without a proper carry bag, it will be very hard for you to carry the machine and its attachments.

If you are taking the product only to use once, then you can skip this step. But in other cases, we recommend getting a product that gives you a nice and handy case to carry the expansion tool kit.

6. Weight

The final and an important criterion of our buying guide is the weight of the product. Taking an excessively heavy product can strain your hand too early before you even do half of your job.

Nowadays, most of the high end and mid range products are lightweight, but again, you shouldn’t buy the product without checking.

How to Install PEX with a PEX Expander?

Installing PEX with a PEX expander is an easy task. You need to have an expansion tool with an expansion ring to place on the PEX tube.

1. Measure the Pipes

Before you start, measure the pipes carefully and cut them in perfect sizes to have a perfect and reliable pex connection that lasts long.

2. Expansion Ring Placement

After cutting the pipe, you should now place the proper expansion ring at the toe end of the pipe. Make sure you are using the current sized expansion ring to use, as slight variation in sizes can ruin your job.

3. Connect the Tube with Expander

Now, connect the tube to the expansion tool head. You may need to get help from another person if your expander is too heavy. With a lightweight PEX expansion tool, you can do it yourself.

4. Expand it

Finally, press the trigger to expand the tube. You need to press the trigger for more than 5 times to get the pipe in a perfect position to take the fittings.

Generally, manual expansion tools require more presses than automatic expansion tools. And the number of presses required is also dependent on the weather condition. Warmer temperatures make the expansion process quick, but the pipe will shrink faster in warm weather. So, you may not get enough time to slide the fittings perfectly if not expanded sufficiently.

On the other hand, you will require more expansion to get the pipe in perfect shape to fit the fittings, it will not shrink fast and will give you enough time to fi the fittings.
