Sealing cone (ferrule) made of chemical-resistant fluorinated plastic ETFE, made of biocompatible, thermically and chemically resistant polytetrafluoroethylene (PTFE), made of high-pressure and temperature resistant polyimide.
For connection of plastic capillaries and tubing with metal-free set-ups.
MULTIFIT®-flanged fittings are pressure- and tensile-resistant tubing connections for fixed installation of tubing on metering systems, chromatographs, automatic analysers, hydraulic and pneumatic units, for pressure and vacuum, for all kinds of media in a wide temperature range. The connection can be established in two ways.
1. Connection by means of an insert:
Advantage: The connection is suitable not only for PTFE tubing but also for flexible tubing such as silicone or PVC.
Joint assembly: The tube is passed through the fitting hollow nut the thread of which points to the tube end. The tube end is expanded by sliding it on the drift of the special tool. A fitting adapter, put on the retaining pin of the special tool, is inserted in the expanded tube end. The tube end inserted into the adapter is slipped into the taphole of the coupling piece and the hollow nut is tightened manually.
2. Connection by means of a thermoflange:
Advantage: Inexpensive and simple connection if a thermoflange machine is available. For PTFE tubing only!
Joint assembly: The tube is passed through the fitting hollow nut the thread of which points to the tube end. A washer is slipped over the tube. The flange is produced within seconds by pushing the tube on the electrically heated drift of the thermoflange machine. The flanged tube end with the washer behind it is inserted in the taphole of the coupling piece and the hollow nut is tightened manually.
