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. -- Craig ________________________________ Message 2 _____________________________________ Time: 04:32:15 PM PST US From: Jim Belcher Subject: Re: Zenith-List: fuel-safe "grease" for Viton o-rings 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.

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.

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. -- Craig _____ From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of Terry Phillips Sent: Saturday, April 03, 2010 10:18 PM Subject: Re: Zenith-List: fuel-safe "grease" for Viton o-rings Craig My memories from years in the lab and industry is that Viton is the el primo elastomer.
