Case Study – PTFE Tube assembly for a fluidic application.


The project criteria: PTFE tube assembly for a fluidic application

The PTFE tube needed to be as transparent as possible so that the medium passing through the tube was visible.  PTFE is generally opaque compared to FEP or PFA.  The overall length was 4 metres and an accurate volume was required and free issue 1/8” fittings, washers and PVC tube needed to be secured to the tube.

The solution: Bespoke flanging process

We have developed several different techniques to create flanges, flares and closed end tip profiles on our fluoropolymer tubing.

For this application we selected an extruded stock PTFE tubing that was produced from a PTFE raw polymer that has superior transparency compared to other grades.

We pin gauged the ID of the PTFE tube (0.8mm ID x 1.6mm OD) to check that it was consistent in size and that the required volume over the 4 metre length would be as accurate as possible.

Using our bespoke flange tool the fittings were applied ahead of the flange being created at each end of the tube.  The flange diameter was designed to match the OD of the washer.

The parts were then coiled and packaged to the customers requirement.

All of our PTFE, FEP and PFA tubing can be made into custom assemblies to suit the end application.
