Food safe lubricant?

[brewkinger]

I have a friend that is a maple sugarer. He gave me a small packet of Dow Corning 111 Valve Lubricant & Sealant.
The ingredients in this stuff:
Polydimethylsiloxane
7631-86-9 Silica, Amorphous
7013167-8 Dimethyl Siloxane, Hydroxy-terminated

Is this what I want to use on my o-rings?

It is sold as an o ring lube on the beer / wine site in the link below. Expensive stuff, too.

I have heard that the usual keg lubes have the same exact ingredients as Vasoline petroleum jelly, but I have never compared the two.

Vaseline is petroleum based, so I would be hesitant to use that on a rubber O-ring or gasket.

My internet has been down most of the day, so I have been unable to search for myself.

I agree that it is expensive though. I happened by the local sugaring supply place today and lo and behold, there was a tube of the stuff about the size of a toothpaste tube:
$30

SWMBO likes a brand called Astro Glide. Doesn't taste too bad in my experience.

Seriously, though, look for plumbers silicone grease at any hardware store. It comes in little white plastic cups. Petroleum jelly will work, but it shortens the life of the O-ring.

Good old silicon grease works fine and is way less expensive.

Clark might be able to hook you up with some “noncaloric silicon-based kitchen lubricant".
