The Different PEX Fittings Methods In Use In PEX Water Delivery Schemes

PEX is a water plumbing scheme made from high density polyethylene tubes. special PEX fittings are employed to link up PEX tubing. PEX tubing is a pliable material that is easier and less pricey to put in, is resistant to corroding and needs fewer fittings than older plumbing schemes.

In cold temps PEX pipes retain their flexibility and do not become delicate and burst. Unlike metal pipes, PEX tubes will not rust and will not build up scale. PEX tubing is energy efficient as well because they will not conduct heat.

PEX tubing is wound around spools. utilizing spools is cost cost-effective because of their reduced 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 need for elbow joints because the flexibility of PEX tubing allows it to be bent to a 90 degree angle. Installation is easy and quick. There are no fumes and safety risks from soldering because there is no soldering needed when you use PEX materials.

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

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 employed for removing rings from tubes or fittings.

Fittings can be made of brass, bronze, copper or engineered plastic but the most familiar 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 employing PEX tubing with PEX fittings has important advantages over metal and rigid plastic schemes. It costs less. It is simpler and faster to put in. Its resistance to erosion and scale makes it last longer.
