Expansion connections are made by using a PEX expander tool to stretch and widen the diameter of the PEX tube before inserting the
end of a fitting. After about 10 minutes, the PEX tubing will shrink back down to create a seal around the fitting. This method only works with PEX-A.

Products Description
PEX a pipe is a cross-linked polyethylene (PEX) product.Cross-linked polyethylene (PEX) tubing provides excellent chemical and corrosion resistance, making it ideally suited for harsh water conditions or aggressive installation environment. By cross-linking(X) the polyethylene (PE), it greatly improves the pressure resistance and the heat resistance of the pipe and it also improves the long-term strength of the pipe efficiently.
PEXa water service line is engineered specifically for potable water .Pexa is resistant to both mineral build-up and corrosion due to soil and water contact.

* PEX is safe and easy to install. No soldering required, which can be dangerous and tricky, especially in tight spaces. Flames are cool, but burning your eyebrows off or your home down is not.
* PEX can be connected to existing copper and galvanized steel water supply lines with the use of fittings—small pieces that link the two types of plumbing together.
* Due to its flexibility less fittings are needed, unlike metal piping which cannot bend.
* PEX is more resistant to cracking due to freezing thanks to its ability to expand.
* Unlike copper and steel pipes, PEX does not corrode, avoiding both water contamination and leaks.
* Water travels noiselessly through PEX, which is not always the case with metal plumbing.
* Different color PEX tubing makes it easy to distinguish between hot and cold supply lines.
* PEX is easy to service and replace, especially if you install a maintenance loop, which includes a loop of extra tubing that allows for cuts—using PEX cutters—and quick fixes.
* PEX is also an inexpensive option compared to copper.

Installation:
Expansion connections
Copper crimping
Copper crimping is one of the most popular methods.You’ll need copper crimping rings and a PEX crimping tool. The copper ring slides over the end of the PEX tubing, then a fitting is inserted into the PEX. The copper ring is moved to the end of the tube over the fitting, so that the PEX crimping tool can crimp the copper ring and tube snuggly in place.
Stainless steel clamps (SSC)
SSC is a method that involves using a ratchet clamping tool to tighten SS rings around PEX connections. The SS ring slides over the end of the PEX tubing before the fitting is inserted, similar to the copper crimpingmethod. Then the ratchet clamping tool is used to squeeze a tab on the ring, tightening the ring around the tube and fitting.
Push-fit connections
Push-fit connections is the quickest method, involving special push to connect fittings that pop onto the end of the PEX tubing,
creating a seal. You don’t need tools to implement push-fittings, although a specific removal ring is necessary to take them off
of a pipe once they’ve been connected.
creating a seal. You don’t need tools to implement push-fittings, although a specific removal ring is necessary to take them off
of a pipe once they’ve been connected.
Compression fittings
Compression fittings involve slipping a threaded brass nut over the PEX tube before sliding a tapered plastic compression ring in
place.Then a hollow brass tube is inserted into the end of the PEX tubing. All of the above is inserted into the end of a threaded fitting, and the threaded brass nut is screwed onto the end of the fitting.The nut squeezes the plastic compression ring against the end of brass fitting to create a seal as it’s tightened.
