I am doing a small trial using hexagonal teflon bushings to protect the exposed ends of some heat exchanger tubes. I will know in about 2-3 months if the trial is successful, and if so I will be looking for 650 or so to do a more extensive evaluation.
The part is essentially a piece of hexagonal teflon stock (unfilled PFA or PTFE acceptable) that is 2" accross the flats and 1-1/4" long. It has a through bore that is 1.215"-1.230" ID, and a counterbore that is 1.495"-1.498" ID by 1" deep.
It is important that the PFA or PTFE material NOT contain glass fiber filler. I have specified virgin material, but reprocessed might be a possibility.
Anyone who is interested in quoting please PM me an email address and I can send you a pdf version of the drawing with dimensions and tolerances.
Thanks,
Jeff
