Why Use HousePEX?

HousePEX Properties

HousePEX pipe has outstanding performance in pipe flexibility & pressure resistance. You can bend our PEX to a 4” radius. Try that with any other PEX and your going to kink it. This means faster and easier installation with a superior result.

How does LK Pex AB make HousePEX?

The raw material used is HDPE (High Density PE ). Due to our unique raw material blend and our peroxide process we achieve a lower degree of crystalline, this makes our pipe more flexible then our competitors. Our very special process technology also enables us to achieve a superior pressure resistance, which qualifies the pipe as a PE-X 100 Material (a PE-X 100 Material has a higher pressure resistance then the requirement for High Density PE-X ).

The practical implication of this is more comfortable and faster installation for you combined with an even higher degree of safety for the user.
