PEX is a water plumbing scheme constructed from high density polyethylene pipes. particular PEX fittings are employed to link PEX tubing. PEX tubing is a pliable material that is easier and cheaper to put in, is resistant to erosion and necessitates fewer fittings than copper plumbing systems.

The flexible pipes are not made brittle by low temps. Polyethylene pipes are cheaper 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 utilised with PEX systems there are no nasty fumes or the risks associated with employing a torch.

PEX tubing is weaved around spools. utilising spools is cost efficient because of their reduced weight and ease of storage. They cost less to transport than other types of pipes. PEX tubing can be installed directly from the reels with no need for coupling fittings. There is also no demand for elbow joints because the flexibility of PEX tubing allows it to be flexed 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.

There are a number of joining methods some of which are patented. But basically the fitting is inserted either over or into the tube and a ring is crimped over the tube or fittings. Rings can be made of plastic, copper or stainless steel. There are proprietary joining systems which require special tools and fittings.

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

Fittings are usually made of brass, although there are some made 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 pipe and the crimped metal ring all work in concert to form a high-pressure seal.

Water plumbing systems that take advantage of PEX tubing and PEX fittings have certain benefits. The materials are less pricey than metal and plastic pipes. Fewer fittings are necessary. The Installation process is easier and shorter. Your system will never corrode or break so it will last longer with fewer potential troubles.
