Types of PEX crimping tools

Thermal plasticity and flexibility of PEX pipes considerably simplifies the process of installation. The latter can be easily carried out with the help of PEX tools by both homeowners and professional plumbers. However, in each case it is necessary to follow the manufacturer’s recommendations, in order to provide the maximum tightness of the assembly. In order to perform the above-mentioned procedure the following PEX tools will be required:

Cutter. It is used to make a straight and even square cut of pipe ends without much effort. The same tool would be suitable for big and small diameters. However, you should prefer a ratchet cutter to a conventional type when dealing with 1-inch diameter pipes or bigger. For instance, the PEX cutter from the IWISS F1807 COPPER RING CRIMPING TOOL KIT FOR 3/8,1/2,3/4,1-INCH is a spring-loaded option with sharp stainless steel blades which makes clean and accurate square cuts with no hassle.

Crimping/clamping tool. It also comes in a hand and cordless design and sometimes features interchangeable jaws/dies to fit various pipe sizes. Such tools can be designated for usage with one particular diameter of PEX pipe in a single-size design. Also, it can come in 2-in-1 design, so as to fit two PEX sizes. The downside of a dual-size crimping tool is in complexity of its use in comparison with a single-size option. Also, PEX crimping tools can be delivered with a kit of replaceable jaws from 3/8" to 1-1/4" which can be selected depending on particular application. Such kits always include go/no-go gauges to verify tightness of a connection which shall be within allowed tolerances. A clamping tool is delivered with stainless steel rings which feature the unmatched corrosion resistance and always come in one universal size; whereas a crimping tool with copper rings come with interchangeable jaws. The entire ring should be tightened, thus requiring more force.

Anyway, both crimping and clamping methods allow achieving equally reliable connections with no leakages provided that they have been performed in a proper way. The cordless MILWAUKEE 2674-22C SHORT THROW PRESS TOOL KIT from out top list is the cutting-edge option demonstrating outstanding power and efficiency.

Expansion tool. Designed for PEX pipe end expansion, this tool allows getting a desired size to drive oversize fittings in place, thus creating a reliable connection. Expansions are offered in hand and cordless designs with different head attachments from 3/8-inch up to 1-inch. And the IWISS PEX PIPE EXPANSION TOOL KIT is a bright example of the advanced PEX tools suitable for cold expansion. It is important to remark that improper expansion of a pipe can cause pipe damage or leakage. Thus, its application would be more preferable for larger professional-grade jobs; as there are a lot of bottlenecks to face with, like material temperature or a holding time before connection becomes totally secure. Thus, a novice user would most probably make a mistake requiring removal and reuse of a fitting which may become a real headache.

Decrimping tool. It is commonly delivered as a part of PEX crimping tool set. A decrimper is used for removal of copper rings from finished connections which have been made improperly, for some reasons. The ICRIMP RATCHET PEX CINCH TOOL WITH REMOVING FUNCTION is an awesome combo of crimping and de-crimping functions in one compact tool.

How to use PEX Crimp tools properly? | TIPs and recommendations

It goes without saying that modern manufacturers of PEX tools and accessories are trying to facilitate the life of plumbing professionals and DIYers making it as convenient as practically possible. A crimp/clamp tool is one of the essentials required for PEX pipe connection. Thus, you should know how to use it following manufacturer’s recommendations before proceeding with further installations. In addition, our general guidelines will be an indispensable prompt on its use in the simplest and most efficient way.

1. First, you should prepare the pipe end using a PEX cutter tool to make a square cut. Check the diameter of a fitting to be driven into the PEX pipe; it should be compatible with its size. Choose jaws of an appropriate outside diameter.

2. All standard sizes of PEX pipes are determined by an outside diameter. Which is why, an inside diameter might come with some slight tolerances. Thus, a pipe can be gauged with a help of a hand or electric expansion tool. To avoid over-expanding of the pipe, do not hold it in the expanded position.

   Important! Some expanders do not provide a sufficient pipe expansion in a single run. For such tools, the process must be repeated several times by rotating a tool by 30°-45°.

   In case if you use a cold expansion method with PEX-reinforcing rings, no other tools are needed. After insertion of a fitting into the pipe until its overlapping with an expansion ring, you should wait till the pipe starts to shrink back to its original size. Simultaneously, it will squeeze tightly the fitting. However, let’s get back to the installation procedure using a crimp/clamp tool.

3. Drive a fitting, either metal or plastic, into the end of the pipe.

4. Take a copper crimping ring or a stainless clamping ring and slide it over the end of a pipe, to the position where it will overlap with a fitting.

5. Using a crimping/clamping tool, compress the copper/stainless ring until the tool stops.

6. Use a go/no-go gauge in order to check if a connection has sufficient tightness to exclude water leakages during pipeline operation. On the other hand, with its help you can determine whether the connection is too tight or not, as this can cause a risk of pipe and fitting damage. Thus, you should slide a “Go” side of the gauge over a ring. If it adequately fits the ring, then you have a leak-free connection.

Things you need to know when working with PEX pipes

Nowadays, PEX pipes and fittings are widely used for hot and cold water supply systems. They are made of cross-linked polyethylene. Creation of cross links implies modification of a chemical structure of plastic which leads to formation of a strength three-dimensional lattice. The latter allows usage of PEX pipes for high pressure and temperature applications which recently have presumed usage of metal pipes only. PEX can be classified depending on cross-linking type (physical or chemical). In particular, PEX-A, PEX-B, PEX-C, PE-RT grades are defined with variation in their features. Some manufacturers produce PEX pipes with color codes which determine a certain scope of applications.

Also, a PEX pipe is very popular thanks to its ultimate flexibility. In case of its allowable expansion the pipe will tend to shrink to its original size. Besides, PEX pipes demonstrate ideal characteristics suitable for a long-term service, and they are highly resistant to corrosion. More than that, PEX features an awesome elasticity to absorb water hammer shock more efficiently in comparison with conventional metal pipes.

Currently, there are four installation methods applicable to PEX pipes: crimping/clamping, pushing, expansion and press. The mounting of PEX pipes and fittings is simple and easy with the help of appropriate PEX tools sets suitable for particular applications. There is no necessity in fusion or welding anymore.

During installation and operation of PEX pipes, try to exclude any contact of the pipe with an adhesive tape, painting or sealing compounds which contain plasticizing agents, as well as with materials with dissolvents. This is connected with a negative effect on PEX pipe properties by certain substances and compounds contained in these materials.

As excessive UV light also has an adverse effect on PEX pipe properties and duration, it is necessary to store and install them avoiding exposure to direct sunlight (UV radiation).
