For the desing of the new "ixPress" fitting we have followed the requirements, established by the european Norm EN154-Part 3a, regarding the acceptable wall-thickness of the fitting and the minimun inside free diameter.

The new "ixPress" fitting fulfills all the requirements established by the ISO 15875 (PEX tubes) and ISO CD 21003 (Multilayes tubes) norms and has succesfully passed all required test such as: continuous pressure test, bending test, high temeperature tensile test, hot and cold water cycle test, pressure cycle test and vacuum test.

Moreover, in order to check the fatigue behaviour of the different plastic polymers, used in the "ixPress" fiting, we have carried out extensive test, wich showed such excellent results, that permits us to guarantee its life for more than 25 years.
