PEX fittings are employed to join the flexible polyethylene pipes used in PEX water plumbing arrangements. resilient PEX pipes are a low cost, trouble free alternative to metal or plastic arrangements. You can head off the troubles of erosion and scaling when you utilize a PEX arrangement. Altogether PEX water plumbing systems are a vast improvement over older systems that use copper or rigid plastic pipes.

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

PEX tubing is stored on spools. Spools weigh less than metal or rigid plastic pipe making them less expensive to ship and easier to store. When used in an Installing, PEX tubing can be unrolled directly from the spool and does not call for coupling fittings. This saves the time and cost of running pipe. PEX tubing can be flexed 90 degrees eliminating the need for elbow fittings. PEX tubing does not need to be soldered so there are no unhealthy fumes and dangers posed by using a torch.

Connecting the pipes is done by inserting a fitting into or over the pipe and then pinching a ring put over the tube or fitting. There are a few unique connection methods. Some use copper crimp rings and others use crimp rings made of plastic. One scheme uses a stainless steel clamp. Most fittings are brass although some are made of other metals or plastic. Because PEX tubing is resilient and can be bent to a 90 degree angle elbow joints are not needed.

Tubes are cut using 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 utilized to remove crimped rings. There are some specialized tools employed for the stainless steel clamps and proprietary connection methods.

Fittings can be constructed 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 utilising PEX tubing with PEX fittings has important advantages over metal and rigid plastic systems. It costs less. It is simpler and faster to put in. Its resistance to corroding and scale makes it last longer.
