Give your local Dupont Performance Lubricants salesman a call. Dupont
makes a line of synthetic greases under the Krytox brand name which use a=
PFPE (perfluoropolyether) oil thickened with PTFE (Teflon). It is rated
for continuous use up to 260 degrees celcius and down to forty below zero=
and is chemically inert, so it won't react with anything which may come
into contact with it (gas, liquid or solid). I think the GPL-225 would
probably meet your needs, but something thicker (GPL-226) might be good,
too. You should be able to get a 'sample' tube of this stuff for about $=
10
or less. I've never used it on a distributor, but I imagine it would
proably work well. Check out: =

r
greases, let me know.
