Unfortunately, our country has not yet approved for mandatory use of precise testing methods for PEX pipe and not all enterprises engaged in their certification, with the necessary stands. Therefore, it is believed that while the domestic certificate of compliance may not always be considered sufficient proof of the suitability of pipe for heating and hot water.

If this does not screw connections, installation of which is carried out by conventional wrenches, it is necessary to install them "corporate" tool. Such devices are also in the range of manufacturers of PEX pipe. The snap-release and specialized companies. For example, Brazetek manufactures devices for pressing fittings, providing them with interchangeable attachments for mounting the fittings of the largest firms.
