Flangeless Fittings: Eenvoudige Montage zonder Flansen

De IDEX Flangeless Fittings zijn de meest populaire oplossing voor het aansluiten van polymeer tubing (zoals FEP, PFA en ETFE) op poorten met een vlakke bodem (flat-bottom). Zoals de naam al zegt, hoeft de tubing niet geflanst te worden. Een eenvoudige, recht afgesneden tubing is voldoende voor een perfecte, lekvrije verbinding.

Waarom kiezen voor Flangeless?

  • Snel en Eenvoudig: Schuif de nut en ferrule over de tubing en draai deze handvast aan. Geen speciaal gereedschap of hitte nodig om de tubing te vervormen.
  • Biocompatibel: Vervaardigd uit inerte materialen zoals PEEK en ETFE, waardoor ze ideaal zijn voor biochemische analyses.
  • Brede Compatibiliteit: Geschikt voor de meest voorkomende flat-bottom poorten zoals 1/4-28 UNF en M6.
  • Drukbereik: Betrouwbaar voor toepassingen van vacuüm tot circa 2.500 psi (172 bar), afhankelijk van de tubing-maat en het materiaal.
