PEX fittings. Types and purpose
PEX fittings – is the connecting part of the pipeline to be installed in places of its branches, bends, transitions to a different diameter, as well as appropriate private assembly and disassembly of pipes. PEX fittings are used for the hermetic connection pipe and other ancillary purposes.
PEX fittings – is an integral part of any pipeline, because even if the pipes run strictly on a straight line (which almost happened), for each of them there is always the starting and ending points in which they are using or PEX fittings are connected to other pipes, connected to anything.
To connect any PEX plumbing PEX fittings are used combined with the details of the polymer metal liner with pipe thread.
The design and material of which is made absolutely every PEX fitting, depends on the properties of the pipe material and the appointment of an assembling of the pipeline. Depending on the purpose PEX fittings are subdivided into several types.
Squares – PEX fitting for changing the direction of the pipe
Elbow, or withdrawal – a kind of PEX fitting, which allows to change the direction of the pipeline for a certain number of degrees. Are there any objections as made entirely of polymer materials, as well as combined.
Elbows differ in the degree of deviation pipe. The standard gon include PEX fittings, pipe deflection by 45 °, 30 °, 90 °. In complex situations, installation is carried out using non-standard taps, which are rarely found on sale.
Tees – PEX fittings for connection of three pipes
Tee – a type of PEX fittings, connects the three pipes together. Tee is usually used if necessary to withdraw the tube from one another at an angle of 45 ° or 90 °. Tees are equal to one diameter of pipe joints, as well as pressure-reducing valves (transition) with connecting pipes to transfer to a larger or smaller diameter.
Crossing
Separately, it should be noted another type of PEX fittings – Cross, providing a branch in four directions. Crossings used when connecting the four pipes. It has four entrances, located at an angle to each other. Traditional form of crosses – all the pipes are located to each other at an angle of 90 ° in one plane. In sewer systems exist dvuhploskostnye crossings.
Couplings – PEX fittings for direct connection of two pipes
Clutch – is the easiest type of PEX fittings, pipe connects to each other, without changing the direction of the pipeline mounted, or replacement of defective parts of the pipe. Clutch is a component corresponding to design and material of pipe, which it connects.
The main function of this type of PEX fittings – solid and tight connection of pipes. Clutches are successfully used for the installation as the same pipes and tubes, differing from each other by material and diameter (using the combined and adapter).
