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

In cold temps PEX pipes retain their flexibility and do not become brittle and break. Unlike metal pipes, PEX tubes will not rust and will not develop scale. PEX tubing is energy cost-efficient as well because they will not conduct heat.

PEX tubing is rolled around spools. utilizing spools is cost cost-effective because of their lower weight and ease of warehousing. They cost less to ship than other types of pipes. PEX tubing can be set up directly from the spools with no need for coupling fittings. There is also no demand for elbow joints because the flexibility of PEX tubing permits it to be turned to a 90 degree angle. Installing is easy and quick. There are no fumes and health perils from soldering because there is no soldering needed when you use PEX materials.

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 connection methods. Some use copper crimp rings and others employ crimp rings made of plastic. One scheme uses a stainless steel clamp. Most fittings are brass although some are constructed of other metals or plastic. Because PEX tubing is pliable and can be flexed to a 90 degree angle elbow joints are not needed.

The tools you will use when installing PEX are a PEX pipe cutter, a main crimping tool and a de-crimping tool. The PEX pipe cutter comes in different sizes for 1/2″ and 3/4″ size pipes. Rings are crimped utilising the crimping tool. The de-crimping tool is utilised for removing rings from pipes or fittings.

Fittings can be made 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 certain advantages over metal and plastic piping. It is less pricey than rigid plastic and copper piping . It can be installed right from the reels. It requires less fittings. It last longer due to it is not vulnerable to erosion.
