Does anyone have any experience with using Dupont's Krytox high-temp grease for both electronics (e.g., sparkplug boots, dielectric grease is burned-up), and as an O-ring lubricant (esp. the Y-pipe O-ring) ?

Dupont even has an application for wheel-bearing grease.

haven't had any experiece with it yet but it sounds like good stuff!!

 

I SUMMON THE GREASE OF KRYTOX!!!

Sorry, I don't have any information about the grease. I just couldn't resist the funny name.

Check out this thread on how using Krytox grease in the wheel hubs has lengthend it's service life.

Looks like NASCAR also uses this grease as well as some racing bikes.

Excerpt:

An alternative to moly is the new poly-flourinated lubricants made by DuPont called Krytox Teflon Bearing Grease. These chemicals are simply magic. They have almost no known solvents, are chemically inert, and don't burn at any temperature, even in a pure oxygen atmosphere. This is pretty clearly the only grease to use. See this article:
http://www.sandsmachine.com/grease_t.htm

NASCAR mechanics have found that Krytox grease can reduce the temperature of spline joints on drive shafts by 150°. Also, this stuff lasts forever. It is, unfortunately, quite expensive.

Krytox is compatible with moly - in fact DuPont sells a high pressure Krytox which mixes the two. You may hear some horror story from some mechanic about mixing greases and the result turning radioactive or some such. Don't worry, it won't happen with moly or Krytox.

Krytox greases:

* DuPont XHT-AC extra high temperature anti-corrosive Krytox. $30 for a 2oz tube, pn 10195K25; $113 for an 8oz tube, from McMaster Carr.

* DuPont XHT-BDX extra high temperature extra bonding Krytox. $63 for a 2oz tube pn 10195K22; $230 for an 8oz tube pn10195K24 from McMaster Carr.

* LocTite Krytox HyperLube, pn 29711. about $35 for two ounces.

 

Yowsa, that's salty stuff. Looks good, but overkill for a lot of things.

Got a particular application in mind?

I can't think of anything grease lubed on my car that would immediately benefit.

Possibly the wheel bearings . . .

I've used it but only when using it for capital semiconductor equipment, i.e. multi-kajillion dollar machines. Probably overkill for just putting around the streets.

 

LOL, why the hell would anyone need that on your y-pipe o-ring? You're a ridiculous person, aren't you?
