6 Best PEX Crimp Tools – Buying Guides & Reviews

PEX is growing in popularity with both Pros and DIYers. Instead of soldering with costly copper piping and torches, you can secure leak-proof joints for these plastic pipelines with clamps and crimps — seams that are quick, simple, and budget-friendly.

These clamps and crimps do need unique tools though. To guarantee you’re creating a well-functioning seam, it’s essential to pick the very best PEX crimping tool for your task. This guide runs through the functions you must think about when looking for a PEX crimping tool.

PEX Crimp Tool Types

Before we compare PEX crimping tools, here’s a little background regarding PEX pipelines. PEX is a versatile type of tubing designed to carry freshwater, warm water, radiant heat, and even water for your sprinkler system, making it preferred in domestic settings.

These plastic pipelines all work in the same manner, and the majority of the very same seams will be applicable for all 3 types, though their attributes and makeup differ. Something to know is that the different types – PEX A, PEX B, and PEX C – do not suggest a level of quality or grade of PEX. Those classifications simply suggest the production procedure utilized to develop the pipeline.


This is the costliest kind of PEX. It comes with some advantages. For one, though it will come in rolled coils, it will take and hold its desired shape when corrected, making it simpler to set up through wall spaces and floorings. It’s bursting pressure is lower compared to PEX B.


This type of PEX normally comes in at half the price that PEX A does, and it comes with both disadvantages and advantages. The bursting pressure is higher, though it doesn’t keep its desired shape as well.


This type isn’t really typical, and most DIYers are not likely to use it. PEX C is fairly weak in comparison to PEX A or B. It likewise doesn’t resist oxidation as well, so it will naturally wear down through typical use quicker than A or B.

How to Choose the Best PEX Crimp Tool

When looking for the finest PEX crimping tools for making leak-proof joints, here are the essential factors to consider to keep in mind.

Crimps and Clamps

There are clamps, and there are crimps. Crimps are copper rings that move over the joint; a crimping tool then squeezes the whole ring tight onto the barbed fitting below. Copper crimps are larger and stronger than clamps, though they’re more vulnerable to deterioration.

Clamp tools squeeze the knob up until a peg is situated in the hole, thereby securing it onto the barbed fitting placed inside the joint. Tools capable of handling both clamps and crimps are unusual, so pick one design prior to buying.


The longer a tool’s handle is, the easier it is to secure or crimp, needing less effort to develop an ideal seal. You generally want to look for a crimp tool that is 11 inches or longer.

Clamps are generally simpler to put in place and require not as much effort, so the handle length isn’t as important as it with crimps.


Prior to selecting a securing or crimping tool, make certain to understand what kind of pipeline it’s suitable for. While numerous kinds of clamp and crimp tools work are for pipe joints, not every one can be used for working with PEX pipeline.

Some tools are designed for use with PEX and copper pipeline, though they usually need extra fittings or jaws. It can become pricey rapidly, but for anyone who works on piping frequently, it would probably be worth the financial investment. Changing the fitting on a clamp tool takes less time it would to sweat a copper seam with solder and flux.


Do not fret about selecting the ideal size of PEX crimping tool. Due to the fact that they can be found in just a few different sizes-(generally 3/8-, 1/2 -,3/ 4-, and 1-inch), almost any clamp or crimp tool produced for working with PEX can work. Switching in between the different sizes is generally quite easy.

Crimping tools usually have a 1-inch jaw for crimping 1-inch pipeline, though their packages feature smaller sized jaws for taking on smaller sized pipelines. To secure those smaller sized pipelines, merely open the jaw and slide the size of jaws you need within.

Clamp tools are frequently designed to fit any size. They move over a knob of the clamp to squeeze it, and the knobs they use are fairly universal.


After finishing a pipe project, it’s not nice to see leakages or malfunctioning seams. It can be challenging to get an idea if there’s a tight seal just by looking at it or feeling it when working with PEX crimps. To make sure each joint finished out properly, some tools feature go/no go measures.

The gauge ought to go over the crimp to about midway before it stops. If it moves up over the crimp, or doesn’t slide up at all, then the seam might have issues when its pressurized. That would mean the crimp either isn’t as tight as it should be or was set up with irregular pressure, so the crimp has become elongated.


Gradually, clamp and crimp tools will slip out of ideal calibration. Applying pressure to the tool throughout a pipe job can extend the jaws slightly, in which case, you’ll want to call them back in.

The majority of the very best PEX crimping and clamping tools have calibration evaluation and modification screws, and they typically include the wrenches needed to change them. Utilize these assessments to identify how far it’s fallen out of calibration, then tighten it back up to the perfect setting. A number of these tools feature adjustments on both sides of the jaw, enabling you to adjust it for a completely round shape.

The gauge can likewise tell if the jaw is too tight, which can also result in a leak.

Removal Function

A lot of the very best PEX clamping tools have a removal function for separating the clamps from the pipeline. Do not anticipate recycling these crimps or clamps, though, since the removal procedure either damages their stability or cuts right through them. The fitting beneath ought to be entirely undamaged.

To take a clamp off, change the tool to its cutting function. Then, move the jaws over the clamp’s knob and tighten up until the clamp tool slices through the band. Take the clamp off.

Getting rid of crimps needs a completely other tool with a blade to cut through copper crimps. If this is the case, then cut the entire seam out of the line, slip the tool up into the fitting, and contract the handles till it makes a complete cut. A second cut from the opposite side will separate it totally.

Considering that crimp cutting tools can cut through copper, it’s crucial to keep your fingers away from the jaws. The threat of copper breaking and ending up being air-borne is very real, so safety goggles are advised.
