Buying Guide For The Best PEX Expander Tool

Are you looking for a decent PEX expander tool, you should take some time out and consider reading our buying guide for the best PEX expander tool given below. Here, we will talk about some of the most important properties of a simple PEX expander tool that matter a lot in its application. Taking note of the following properties will allow you to select a proper option according to your application without spending a significant sum.

As you can easily get the best option by carefully choosing the right properties, you can avoid incompatible options. Go with the best option needed for your work in your budget. The PEX expander tools are designed for a longer lifespan and come at quite an expensive price tag. Thus, you should definitely spend some time understanding the product before you buy it so that you won’t have to return or replace the tool after getting it. Here are the most important properties of a PEX expander tool.

1. Expansion Heads

The expansion heads used with a PEX expander tool are the only variable parameters that allow you to use the tool with different types of pipes. Generally, the PEX expander tool kit comes with 2 to 3 types of expansion heads included in the package that covers all general applications. But, having additional expansion heads allows you to increase the versatility of your tool regarding different types of applications. Also, the expansion head basically dictates the possible type of fittings available with the tool kit.

2. Mode of Operation

Mainly, there are 2 types of PEX expander tools available in the market that are manual and electric tools. In the electric type of PEX tools, you can further choose between corded and cordless modes of operation. Choosing an electric option over manual tools has a lot of advantages. First of all, you will not need to apply any force on the tool as the built in electric motor will take care of that. Secondly, these tools are precise as well as fast in comparison with manual tools. But, electric tools are available at a very expensive price tag which is not ideal for a simple tool like a PEX expander tool. Also, cordless electric tools have limited battery life and cannot be used for long working sessions.

3. Overall Build Quality

The build quality of any tool is highly important. The general rule of selecting a tool is to make sure that the material used for the tool is harder and tougher than that of the workpiece. That also applies to the PEX expander tool kits because you will be putting enormous pressure on the tool either manually or by the electronic motor. Thus, there is a high chance of failure if the tool is not stronger than the pipe you are trying to expand. Also, the design of the tool plays an important role here as you need to avoid the tools that have sharp corners and reduced cross-section as these areas are potential for stress concentration which can introduce failure.

4. Carrying Case

The carrying case for a PEX expander tool allows you to carry the tool along with its essential accessories to a distant location without any problem. Generally, the PEX expander tool kits are already very compact in design which makes the carrying case even better for traveling.

Although, the carrying case also needs to be durable to support casual drops, shocks, and impact without damaging the accessories placed inside. In fact, you should look for a PEX expander tool kit that features additional slots for storing extra accessories that you can buy later on. This way, you can store all of the needed accessories in one place and carry them to the workplace without any problem.

5. Ergonomics Of The Tool

The design and ergonomics of the tool are very important, for both electronic as well as manual tools. In the case of a manual tool, having a user friendly design will grant you a secured grip on the tool which often reduces the force required for application. Also, it does not cause strain on the hands even after a long session. As for the electronic tools, the ergonomics are still important considering the design allows you to reach harder places without struggling. This makes the job faster, easier, and more accurate for both experienced as well as fresh operators.

6. Tubing Size

Selecting the correct PEX tubing size is vital for successful plumbing projects. The 3/8-inch size is ideal for small fixtures, while the 1/2-inch size is versatile and suitable for most homes. For larger fixtures requiring high flow rates, the 3/4-inch size is preferable.

3. What is the limit on the number of times PEX A can be expanded?
