PEX fittings are employed to connect the supple polyethylene pipes utilised in PEX water plumbing schemes. flexible PEX tubes are a low price, problem free alternate to metal or plastic schemes. You can head off the problems of corrosion and scaling when you use a PEX system. Altogether PEX water plumbing systems are a vast improvement over earlier schemes that use copper or rigid plastic pipes.
The main advantages of PEX tubing is its ability to stay pliable in cold temps, its resistance to scale build-up and corroding and its lower cost compared to copper or rigid pipes. PEX tubing is less pricy than copper pipe, calls for less time to put in and needs fewer fittings.
PEX tubing is wrapped in spools. Because reels weigh less than cut metal or plastic pipes, they are easier to store and cost less to ship. Tubing can be unwound from the spools with no need for coupling fittings. Installing is much quicker and less pricey when it does not involve the running of pipe.
Connecting the pipes is done by placing a fitting into or over the tube and then pinching a ring put over the tube or fitting. There are a few unique connection methods. Some use metal crimp rings and others utilize crimp rings built of plastic. One arrangement uses a stainless steel clamp. Most fittings are brass although some are built of other metals or plastic. Because PEX tubing is pliable and can be turned to a 90 degree angle elbow joints are not needed.
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 mixture of main crimping tools available which can crimp 1/2″ or 3/4″ pipes. A de-crimping tool is used to remove the copper crimp ring from the tube and fitting.
Fittings can be built of brass, bronze, copper or engineered plastic but the most common 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.
Employing the system of PEX fittings in addition to PEX tubing has distinct advantages over metal and plastic piping. It is less costly than rigid plastic and copper piping . It can be put in right from the reels. It needs less fittings. It last longer due to it is not vulnerable to corroding.
