PEX fittings are used to link up the flexible polyethylene pipes utilized in PEX water plumbing arrangements. flexible PEX pipes are a low cost, trouble free alternate to metal or plastic systems. You can avert the troubles of erosion and scaling when you utilize a PEX arrangement. Altogether PEX water plumbing arrangements are a vast improvement over older schemes that use copper or rigid plastic pipes.

The main advantages of PEX tubing is its ability to remain flexible in cold temperatures, its resistance to scale build-up and corrosion and its smaller cost compared to copper or rigid pipes. PEX tubing is less pricey than copper pipe, needs less time to put in and involves fewer 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 wound off from the spools with no demand for coupling fittings. Installation is much quicker and less pricey when it does not involve the installation of pipe.

Connecting the tubes is done by placing a fitting into or over the tube and then crimping a ring laid over the tube or fitting. There are a few different joining methods. Some use copper crimp rings and others utilize crimp rings built of plastic. One arrangement uses a stainless steel clamp. Most fittings are brass although some are constructed of other metals or plastic. Because PEX tubing is flexible and can be bent 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 assortment 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 can be built of brass, bronze, copper or engineered plastic but the most popular 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 important advantages over metal and rigid plastic schemes. It costs less. It is easier and faster to put in. Its resistance to corrosion and scale makes it last longer.
