Actually it repels both, it's fluorinated (PTFE = poly-tetrafluoroethylene aka teflon) so it's neither hydrophobic nor oleophobic. If it didn't repel oil all your non stick PTFE coated baking trays wouldn't work. Plumbers use it because it's thin enough to fill the gaps in the swagelok threads not because it specifically repels water.

not sure about that.... iv always known it to repel water, and engineers have told me that its no use on fuels (oils) when i was making a biodiesel reactor
Well if you won't believe me (I'm a chemist by the way), how about the manufacturers, DuPont own Teflon and they say it "repels most water and oil based liquids".

If you don't believe them go and put some oil onto a non stick baking tray and prove it to yourself.
