ITAP-FITŪ
THE PUSH-FIT FITTINGS THAT BEAT EVERY RECORD
Itap-Fit® is the innovative solution introduced by Itap for the fast connection of copper pipes and now of cross-linked polyethylene (PEX) and poybutylene pipes as well: one single fitting for three different pipes.
Itap-Fit® consists in a complete range of fittings able to solve the problems generated by any sort of installation. The range is now integrated by the connector art.618, complete with an o-ring, particularly suitable to the use with the range of manifolds and with the valves and lockshields for radiators Itap.
Tests performed in Itap laboratories have proved that the employment of Itap-Fit® to carry out copper pipe installations allows substantial savings of time incomparison with the conventional solutions: 45% less compared to press-fit fittings, 70% less compared to compression fittings and as far as 90% less compared to traditional solder fittings. And all that without the employment of any kind of equipment or special tool.
The whole Itap-Fit® push-fit fittings range, among the widest in the market, is approved by WRAS (GB) for the use
of cross-linked polyethylene (PEX) and polybutylene pipes, as well as with copper pipes.
Such approvals come alongside those issued by CSTB (F), DVGW (D), Kiwa (NL) and Laboratorio Trentino (I) to guarantee the safety of use and technological features of the system.
EASY, CONVENIENT AND RELIABLE INSTALLATION
The use of Itap-Fit® fittings is easy and intuitive, and their installation does not require any complex tool or skilled worker: despite this, the connection is completely reliable and it is almost impossible to make errors during the installation if you just follow the 5 simple steps explained below.
The most important component of the fitting is its fastening ring of stainless steel, whose shape, that was developed after a long study and many trial tests, basically prevents the installed pipe from being accidentally extracted, and, in the meanwhile, allows its very quick release by just pushing the release sleeve with the lever (art.670) or the clip (art.671), without the slightest damage either to the pipe or the fitting.
1. Cutting the pipe.
You first need to cut the pipe by a rotary pipe cutter such as art.675. Do not use any hacksaw. Should the end of
the pipe be ovaled or otherwise deformed, it is necessary to cut it as far as the end of the pipe appears free from
any imperfection. In case of a lined pipe it is necessary to remove the lining over the whole portion that will enter the fitting.
2. Deburring.
The second step is deburring the external surface of the pipe by a berurring tool such as art.680. Burrs on
the external surface could damage the o-ring and therefore jeopardize the seal.
3. Using the depth gauge.
Once the pipe is ready to be connected, it has to be inserted into the depth gauge (art.685) and the depth of insertion shall be marked on the pipe. This shows the correct insertion depth of the pipe into the fitting and therefore allows to make sure that the connection was carried out properly.
4. Inserting the pipe.
After a check of the inner cleanliness of the fitting, you shall insert the pipe by pushing as far as it reaches the
blocking point that, if everything was performed properly, should correspond to the mark made before. If you are using cross-linked polyethylene pipes (PEX) or polybutylene pipes you have to insert the liner art. 655 into the pipe before it is connected to the fitting. Now you have a safe yet easily reversible connection. We reccommend not to use any lubricant, as this might damage the o-ring, that is however treated by an alimentary-grade lubricant.
5. Releasing the fitting.
To release the fitting is simple, fast, and free from damages to both the pipe and the fitting.
Both of them can be reused without any inconvenience. To disconnect the fitting you just need to push the release liner by the lever art.670 or the clip art.671, and at the same time pull the pipe. The extraction is not going to involve any trouble at all, provided that you push the liner enough so that the teeth of the fastening ring are well separated from the surface of the pipe.
