| Subject: | fuel-safe "grease" for Viton o-rings |
I'm mounting fitting adapters on my Andair gascolator and they seal to the
body with Viton o-rings. I'd like to replenish the film of grease on the
o-rings and am wondering what kind of grease to use. Searching on the web
indicates that silicon grease can be used on Viton o-rings but it is not
clear if the grease is fuel-proof. I'll send a query to Andair on Monday but
I was wondering if anyone had any advice. If there is a recommended product
a source would be useful too.

I'm not certain about gas slowly removing it, but I can tell you that the only
thing I was ever intentionally able to remove silicon grease with was MEK.

Thanks. Do you think I could get my engine to run on MEK? :-)

I doubt it. But we may have to if the feds keep fooling around. :-)

My memories from years in the lab and industry is that Viton is the el
primo elastomer. It is a fluropolymer, like a rubbery teflon, and it is
impervious to most solvents. I cannot imagine that silicone grease would
cause any problem. My home water filter has common neoprene or whatever
O-rings and they recommend silicone grease for them. However for my fuel
system fittings, I'm planning on use EZ-Turn which is supposed to be fuel
resistant. EZ-Turn might be a good choice for your O-rings.

I'm using EZ-Turn on my metal-to-metal pipe thread fittings. But I think
part of the purpose of the existing grease on the o-rings is just that: to
grease the parts to allow them to slide together without pinching the
o-ring. EZ-Turns is great stuff but is very sticky and doesn't strike me as
a very good grease. Anyway I'll give Andair a chance to reply next week.
