PEX is a water plumbing system manufactured from high density polyethylene tubes. special PEX fittings are utilised to join PEX tubing. PEX tubing is a flexible material that is easier and less costly to put in, is resistant to corrosion and calls for fewer fittings than pvc plumbing systems.

The main advantages of PEX tubing is its ability to stay resilient in cold temps, its resistance to scale build-up and erosion and its lower cost compared to metal or rigid pipes. PEX tubing is less pricy than copper pipe, calls for less time to put in and necessitates fewer fittings.

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

There are a variety of connection methods used in installing PEX schemes. Some of these methods are proprietary and a few require particular tools. Basically, the fitting is placed over the tube or in the tube and then a ring is pinched around the pipe or fitting creating a tight fit. The rings can be built of various metals or plastic depending on he joining method.

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 employed to remove the copper crimp ring from the tube and fitting.

Fittings are commonly built of brass, although there are some built of bronze, copper and engineered plastic fittings for PEX plumbing. There are typical ridges on the “insert” part of the fitting. The ridges, the PEX tube and the pinched metal ring all work together to form a high-pressure seal.

Water plumbing systems that take advantage of PEX tubing and PEX fittings have definite benefits. The materials are less costly than metal and plastic pipes. Less fittings are needed. The Installation process is simpler and quicker. Your system will never corrode or break so it will last longer with fewer potential problems.
