PVC fittings or poly vinyl chloride units are items that are used with PEX tubing in numerous plumbing systems. Traditionally, there were items made with copper used in any kind of plumbing system, but to overcome their limitations, now items made with PVC are used.

Just like any PEX fitting, these units are also inclusive of other pieces also such as elbows, couplings and tees. Although they are similar in appearance to PEX fittings but there is one difference that they are made up with PVC. This is a plastic like material that possesses high resistance to breakages and leakages which is why it is used in all kinds of applications that require great strength and long lasting durability. For this reason, it is used for making all kinds of PVC fittings that can be used along with tubing and piping systems.

Mainly couplings, tees and elbows are considered as fittings that are used in carrying out the plumbing systems. They are used as fittings to join two or more connections or to extend a single pipe line to the requisite length. This helps in supplying water to the desired location. In addition to this, the PVC fittings are also units to be used for increasing efficiency of a water plumbing mechanism. They are robust yet compatible units that can be installed with ease. It is also easy to supply water through them without any kind of noise, thereby improving the overall working of the water supply system.

PVC is considered as one of the finest material to be used in water supply systems after PEX. It is not only robust and strong like it but it is also flexible and can be used for any kind of water supply system. Best thing is to make use of PVC fittings and PEX tubing in a single system so as to make it more strong and versatile.

Although PEX tubing appeared on the Chicago market relatively recently, only about 15 years ago, they are becoming more popular, gaining popularity at the expense of clear advantages over metal pipes that were set before them.

There are several types of PEX tubing. The most popular are: PEX tubing, followed by PVC fittings and PEX tubing. To mount any type of pipe PEX fittings and requires appropriate PEX tools.

The superiority of PEX tubing including PEX, is a number of their properties: durability, cost, resistant to corrosion, the ability to pipe to stretch without losing quality, lack of reaction on contact with water, easy to install, environmentally friendly, no sound operation of pipes.

For each type of pipe PEX fittings provide relevant: for sewer systems from PVC using PVC fittings, for pressure systems from the PP used brass PEX fittings. Assembling these types of PEX fittings mainly differs from the metal, as occurs with the help of welding machines.

All PEX fittings, their types must meet the sanitary requirements and standards that are adopted for these devices.

If you followed all the rules of operation, then Metal PEX fittings are used for a long time, reducing the risk of accidents to a minimum, because they have excellent corrosion resistance, strength characteristics of the store.

Installation of pipes, including metal, if it is carried out using components such as metal-PEX fittings, high-tech, takes at least time-consuming professionals.

PEX fittings of each type on the market in a very large assortment. The cost of the PEX fittings on the market is acceptable, is not high, commensurate with their quality.

During production, all metal-PEX fittings are quality control, so getting them can be asked about the presence of relevant certificates. Manufacturing PEX fittings involved a large number of both domestic and foreign manufacturers

The problem of “residual water” when connecting to the house. Repair sleeve (Fig. 3) decreases in the assembled condition the possibility that the “residual water” in the zone of welding due assembled into a sealing circuit. Integrity is preserved under the pressure reached about 1 bar. A prerequisite for the application of repair bushings is their convenience for use in any part of the PVC pipe fittings due to the great flexibility. Nevertheless, their use is limited to diameters of 32 to 63mm in SDK 11.

The problem of “residual water” at Ø> 63 mm. Technology use is limited to repair sleeves 63 mm due to the inflexibility of large diameter pipelines and related complications installation. Another way to prevent residual water in the zone of welding is common in the area of gas technology installed locking ball, which is due to the high flexibility allows to overlap the different diameter PEX pipe. To install a shut-off ball, you must first drill a hole in the pipe. The drill is inserted through the nipple pad (Fig. 4). This pipe-lining can be welded to the tube and after the repair is brewed using plugs. An alternative may make  PVC fittings, which is dismantled after the frame, and cut a hole sealed amplifying gag-strip. This way you can avoid standing water which can gather under the dome of the pipe-lining. Locking ball significantly reduces the likelihood of “residual water in the zone of welding. It should be noted that before closing the ball should not be pressure, ie, water storage should be derived through the drilled hole. After completion of the frame or repairs with the help of plug-in of fitting parts or movable clutch locking ball is pulled from the pipe, and the hole sealed by one of the above methods (Fig. 5). After the expiry of the cooling of parts and washing water, he is again ready for operation.

Alternative locking ball – film cap. New discoveries in the field of film technology offers an interesting alternative to installing a shut-off ball – water soluble film. They reduce the possibility of water in the area of welding at a certain time, and then dissolve in it. The membrane consists of a non-toxic polyvinyl (PVAL) and polyethylene insert that is authorized for use in potable water. To mount the film membrane (Fig. 6) is introduced into the open end of the pipeline. Compaction occurs due to the integrated sealing jaws. After the restoration of the pipeline remains film membranes are washed out during the flushing water.

In the past few decades, polymers have become one of the basic materials for the production of PEX pipe throughout the world. These PEX pipe have ushered in unprecedented first level of reliability and efficiency of water supply, PEX radiant heating, sanitation and transportation of various media. But the potential of PVC is far from exhausted, constantly creating new, better songs and developed new high-tech types of PEX pipe.

History of PVC fittings is calculated over the centuries. During this time they have come a long way from the tubes of cane to multicomponent systems, can withstand high pressure and high temperature.
