Utilising PEX Fittings To Put In A Better Plumbing System

The flexibility and strength of tubing made of high density polyethylene material and coupled by PEX fittings offers many advantages over plumbing arrangements using metal or rigid plastic pipes. PEX tubes do not corrode and withstand cold temperatures without becoming brittle. They cost less than metal or plastic piping. They are much simpler to put in because they are stored in reels and need fewer fittings.

The main advantages of PEX tubing is its ability to remain pliable in cold temps, its resistance to scale build-up and erosion and its smaller cost compared to copper or rigid pipes. PEX tubing is less pricy than copper pipe, involves less time to install and necessitates less fittings.

PEX tubing is wrapped in spools. Because spools weigh less than cut metal or plastic pipes, they are easier to store and cost less to ship. Tubing can be unwound from the reels with no demand for coupling fittings. Installation is much quicker and less costly when it does not involve the installation of pipe.

There are a number of joining systems some of which are patented. But basically the fitting is placed either over or into the tube and a ring is pinched on to the tube or fittings. Rings can be made of plastic, copper or stainless steel. There are proprietary joining methods which require specific tools and fittings.

Three basic tools are required for the standard crimping method when working with PEX: a main crimping tool, a pipe cutter, and a de-crimping tool. The pipe cutter tool cuts the tube before putting it into the fitting. There are a variety of main crimping tools available which can crimp 1/2″ or 3/4″ tubes. A de-crimping tool is utilized to remove the copper crimp ring from the tube and fitting.

Fittings can be made of brass, bronze, copper or engineered plastic but the most frequent material in PEX plumbing is brass. The fittings have ridges designed to form a tight fit. When the ring is crimped over the tube or fitting a high-pressure seal is formed.

It is clear that utilising PEX tubing with PEX fittings has significant advantages over metal and rigid plastic schemes. It costs less. It is simpler and faster to put in. Its immunity to corrosion and scale makes it last longer.
