As an alternative to DIN 11853 and DIN 11864, KIESELMANN aseptic tube connections provide considerable advantages in technical respects and also regarding costs. The patented k-flex sealing system offers not only a 100 per cent hygienic safety, but also a much wider application spectrum compared to elastomers. Moreover, you can retrofit your DIN 11851 screw connections already built-in by means of a retrofit kit into an aseptic tube connection.
