Can anybody comment on the effect of the teflon coating for high vacuum service?

Teflon is fine in high vacuum service as long as no plasma or beams get near the stuff. Needless to say the stuff is not bakable beyond about 400 degrees. Really deep vacuum stuff (10e-9 torr of better) just has to be baked or the pump times go on forever. The fittings you have were probably meant for 10 microns and higher pressures.
If the number and type of fittings which you have which would be useful in a fusor total more than say $200.00, if bought in solid SS, then I would probably use them, but if you could buy at full list price all of the fittings for under 200.00 I'd go for the pure metal.
