PEX is a water plumbing arrangement manufactured from high density polyethylene pipes. particular PEX fittings are used to link PEX tubing. PEX tubing is a pliable material that is simpler and less pricey to put in, is resistant to corrosion and requires fewer fittings than older plumbing systems.

The pliable pipes are not made brittle by low temps. Polyethylene pipes are less costly than metal pipes and are simpler to put in because they do not use as many fittings as metal or rigid plastic arrangements. Since soldering is not utilized with PEX arrangements there are no nasty fumes or the risks associated with using a torch.

PEX tubing is wound around reels. employing spools is cost efficient because of their lower weight and ease of warehousing. They cost less to transport than other types of pipes. PEX tubing can be put in directly from the reels with no need for coupling fittings. There is also no demand for elbow joints because the flexibility of PEX tubing permits it to be bent to a 90 degree angle. Installation is easy and quick. There are no fumes and safety hazards from soldering because there is no soldering needed when you use PEX materials.

There are a mixture of joining methods utilized in installing PEX schemes. Some of these methods are proprietary and several require special tools. Basically, the fitting is set over the tube or in the tube and then a clamp is crimped around the tube or fitting making a tight fit. The rings can be built of various metals or plastic depending on he connection method.

Tubes are cut utilizing a specific PEX pipe cutter and come in different sizes to accommodate 1/2″ or 3/4″ pipes. A main crimping tool is utilized to pinch the rings over the pipe or fitting. There is a de-crimping tool that is used to remove crimped rings. There are some specialized tools used for the stainless steel clamps and proprietary joining methods.

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

It is clear that utilizing PEX tubing with PEX fittings has crucial advantages over metal and rigid plastic arrangements. It costs less. It is easier and faster to install. Its resistance to corrosion and scale makes it last longer.
