Gerpex system is composed by PeX/Al/PeX multilayer pipes and press fittings. Gerpex is available with press fitting and screw fitting, and it can be used in under floor heating systems, radiator heating systems, fan-coil systems, potable water distribution systems, and compressed air distribution systems. In some countries the last standards (to be verified country by country) are allowing the use of multilayer pipe and press fittings systems for gas domestic distribution.

How is it possible to understand that the jaws of a press machine for press fittings must be replaced?

The jaws must be replaced when, after pressing it, the stainless steel sleeve is not circular, and shows a deformation where the jaws are joining each other.

When is it necessary to check the electric engine of a press machine?

The last generation press machine are equipped with a display which shows the number of operations done and the need of a check.

Is it possible to use PeX/Al/Pex multilayer pipe in solar applications?

PeX/Al/PeX multilayer pipe cannot be used in solar applications, first because it is not UV resistant, and secondly because in case of problems the temperature can be very high and damage the internal layer of the pipe.

Which is the difference between PeX/Al/PeX and PeRT/Al/PeRT multilayer pipes?

PeX/Al/PeX multilayer pipe is composed by crosslinked PE, so the heat and mechanical stress resistance are improved during the crosslinking procedure. PeRT/Al/PeRT multilayer pipe is composed by PE with a chemical additive, so that it can be used with hot water, but it is not crosslinked. PeRT/Al/PeRT multilayer pipe is generally used in under floor heating and under floor cooling systems.
