I just got the latest issue of Bike Nashbar & noticed they've clearanced their remaining stock of DuPont Teflon lube again. At 50 cents a tube, it's the lowest I've seen them go.
This stuff is 100% DuPont Teflon, with absolutely no other additives mixed in. DuPont originally sold it about 10 yrs ago as a bicycle lubricant at $13 for an 18g (a little over 1/2 oz) plastic syringe-type applicator. They offered it in two "weights": a thick grease ("paste"-like) for bearings, & a thin grease (more "sauce"-like) for cables, pivots, & hand-working into chain links. All Nashbar has left is the thinner version.
I looked for this stuff a few years ago, hoping it was still being marketed under a different application, but the closest the folks at DuPont could get me was their Krytox lube, which is a wax-type liquid with solvent-based carriers & only 25% Teflon. Nashbar is the only place I've seen it offered in the past few years, but that doesn't mean it isn't sold somewhere else too. It's excellent for rebuilding sports equipment (fishing reels, skate bearings, etc), lubricating cables, linkages & pivot points on cars, & on just about any small sleeve-type or slide-type bearing surface.
Even though the thin grease is thicker than any oil I've used, it still gets flung out of unshielded, hi-rpm applications (such as ball bearings which see high centrifugal forces). Also, Teflon is not a good extreme-temperature/pressure lubricant, so it shouldn't be used in those applications where stuff like molybdenum is traditionally an ingredient.
Shipping's the most expensive part, so just order enough to feel good about it. Or, justify it by getting some energy bars at the same time to keep in the glovebox for "winter emergencies."
