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?
 
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.
 
i use this product

Picking up this thread again: if I want to insert a 24" racking cane through the hole in a carboy bung/stopper, for a (hopefully) oxygen-free transfer, it seems I would want to lubricate it, to avoid damage to the parts from friction. The product from Hayes listed above seems to be a food-grade grease, which is good, but I keep picturing something like lard or Crisco, which doesn't seem right for my wort. Any thoughts? Is there a better product for this? Thanks.

Wait, WHAT? Is this Tinder? 🤭
 
Fwiw, I use this non-petroleum product:

On keg o-rings and such.
Hmmm it saying it's vegetarian doesn't mean you can eat it safely. Does it even tell you the ingredients? I'm not saying it's not food safe, but manufacturers love to use "green" and healthy sounding adjectives to imply good for you qualities when the terms aren't applicable. Like non-fat for instance but the product has 10,000 calories from added sugar with no chance of any fat in the first place. As a vegetarian, I would be concerned about using something made from animals, but "vegetarian" doesn't mean no animal products. It could have eggs or dairy or honey maybe even. I'm not sure if "vegetarian" is a regulated word even in the food industry. On a lotion I wouldn't trust it to mean food safe, which may be regulated or have a standardization authority.

  • Moisturizes and soothes dry skin
  • Gently removes eye make-up
  • Made from only pure plant oils and waxes
INGREDIENTS: Ricinus Communis (Castor) Seed Oil, Helianthus Annuus (Sunflower) Seed Oil¹, Beeswax/Cera Alba, Tocopheryl Acetate [Tocopheryl acetate is a stable, synthetic form of Vitamin E that functions as an antioxidant and is used in cosmetics and health products to protect against cell damage and premature aging, though high oral doses may cause side effects like dizziness or digestive issues. It is the ester of alpha-tocopherol and acetic acid and can be found in skin care products, serums, and oils, and can also be consumed through certain foods such as spinach, nuts, and kiwifruit.]

I prefer simple unflavored silicone lube ;) but I don't think there's anything in that skin moisturizer that's going to hurt anything...

Cheers!

that was my first thought also

I totally get this. I chose it because I only knew that "keg lube" was petroleum jelly, and this stuff turned up as a non-petroleum alternative at a market where I shop. Seems unlikely to cause harm. My thanks to @day_trippr for posting the ingredients!

It turns out there's various ways to lubricate o-rings. I imagine vegetable oil would work okay, for example. Or silicone, sure.

Ingredients look OK but not everyone likes castor oil.

For what it's worth; When I did my first closed transfers in a carboy I used one of those orange caps;
PTRCarboyPremium-2T.jpg

..I wanted to draw from the top down to avoid disturbing the trub so I started with the racking cane pulled up near the top and slowly lowered it as it drained.. To lubricate, I just sprayed it with Star San.. I know; Not a lubricant, but it made it slippery enough to slide down easily without losing gas.
Oh; The above pic is from brewhardware: https://www.brewhardware.com/product_p/ptrcarboypremium.htm
(it's a lot neater than the cobbled together version I had :p )

awesome— thanks. this is very helpful. I have the orange cap, too, and I think I can cobble something together like the photo suggests. And I feel better using StarSan than some kind of grease.
 
Keep an eye on the carboy cap over time: I left a purple one in my Star San bucket overnight once and had to toss it because it was then too big to fit the 6-1/2 gallon carboy neck.
Thanks for mentioning that! Star Sans' reactivity to silicone and plastics other than PET or HDPE is too often overlooked and you just shone a light on something that was nagging the back of my brain in another thread.

Interesting. My latest batch went through a full and healthy fermentation without the airlock ever bubbling. I was using the orange carboy cap and 3-piece airlock, with the other port capped off. I concluded that there must be a leak with the cap somehow (maybe just slippery from the Star San?) and I didn't sweat it because I knew that fermentation would give me a nice CO2 blanket. But now I am racking out of that vessel to lager in a different vessel that is (hopefully) more airtight. Makes me want to do the bubble test, like we do with our gas grill tanks and connections, to check for leaks on all of these things.
