Could anyone please make recommendation on where to purchase bulk quantity corny ball-lock post silicone o-rings? Thanks -
Thanks for the reply - I'm learning a lot here. Could you kindly post a link to your preferred place to purchase those in bulk? Thanks -I would opt for EPDM which is far superior to silicone wrt both O2 ingress and basic longevity, and in modest ways more resilient and wear-resistant than Buna-N.

Are you sure? I've been changing out my kegs to those red silicone rings for the QDs and tube posts. I find a lot of the old black o-rings get hard and crack.But if one really wants to use silicone, do not use "keg lube" on them as the silicone grease will slowly dissolve the silicone O-rings

And I use food grade "keg" lube.
The lid o-rings I've swapped to silicone as well since they seal better.
I've seen all the posts about silicone letting O2 thru but I am skeptical. If so, why don't the kegs go flat?
Are you sure?
yeah yeah,
Why is any question "silly"?Silly question...
Note that these are different sizes than the one I guessed wildly at.Here's Buna-N o-rings for ball lock that I use, probably the best for the least oxygen ingress. Dip tube and lid are the better x profiles and NOT round.

Yeah...I'm pretty sure I'm right there with you...it's just that if you mention O2 at all, you risk getting pages of arguments from the O2CD crowd..Not meant in a derogatory way at all!..I've learned a lot from some of those heated arguments, but...I just don't care about it that much, I take reasonable care in my brewing to control O2 exposure and it's good enough for me, yet despite wanting to not see another thread derailed by O2 arguments, here I am derailing.yeah yeah,
Yes, silicone is more permeable than neoprene or EDPM. But kegs are pressurized. If O2 is gonna get in, something has to get out? And CO2 is 2 parts O anyway.
Yup... and sooner or later someone will be O2CD enough on here to realize that the spout on thier tap and their beer-glass is full of O2 and we'll see a DIY on a CO2 purging mod for nukataps and the recieving glass (probably relying on the mythical 'CO2 Blanket')Don't forget the chromium oxide covering all the stainless steel. That's got oxygen in it, too. And then there's water, which is only 1/3 oxygen by atom count, but more than 88% oxygen by weight.
Thanks! I had the same thing happened and didn't bother thinking too much about why.. I just decided to stick with either Buna or EDPM.But if one really wants to use silicone, do not use "keg lube" on them as the silicone grease will slowly dissolve the silicone O-rings and cause them to leave deposits in QDs that will harden over time. I once obtained some blue post O-rings, didn't know they were silicone, and eventually had one glue itself to the beer QD on a keg
Hey, thanks for this! Found a keg post ring leaking my favorite stout last week, when I came back for a refill.Here's Buna-N o-rings for ball lock that I use, probably the best for the least oxygen ingress. Dip tube and lid are the better x profiles and NOT round.

Glad it helped. I keep them on my kegging cart and swap out at least post o-rings more frequently now. On the individual keg tags I'm even tracking full rebuild dates, I was getting slack about it for a while until I lost half a bottle of co2 in the cooler.Hey, thanks for this!

Placed my order, and they said it would deliver tomorrow! (Not far from Atlanta to northern South Cackalacky.) I’m anxious to try try the X lid rings; periodically have trouble with the round ones.
Really appreciate this
One the one hand I can agree, but up to a point; When I bottled, kegging sounded like an expensive hassle, and it is, but...with bottling there's much heavier labour and care involved that don't play well with my physical limitations so for me and my circumstance, the journey into kegging has been therapeutic and satisfying. If you still have your health (both neurological and physical), then yes..stick with bottling! But, apart from constant issues posted here with incomplete cap-crimps and correct caps, the value of 'O2 absorbing caps', the type and quantity of sugars, the times and environment for correct bottle-conditioning, the faulty bells on cappers and downright breakage of cheap bench cappers, and even this;Threads like this one make me chuckle just a little at the whole "kegging is so much easier" trope. AFAIK, nobody worries about whether they're using the wrong O-rings on their bottle capper.
Well, "up to a point" is plenty. Since I was joking and all. I constantly amuse myself by doing things in other hobbies that are supposed to simplify a process, only to find that they just add a different kind of complexity.One the one hand I can agree, but up to a point
These guys are tops! I ordered yesterday morning right after I saw your post. I opened my door shortly after noon today and they were on my steps!Here's Buna-N o-rings for ball lock that I use, probably the best for the least oxygen ingress. Dip tube and lid are the better x profiles and NOT round.

With multiple kegs, I have decided that the easiest way to keep up with time in service is to just use permanent marker on the keg. (Permanent marker comes off stainless steel with, uh alcohol. )

Thanks for those replies. Yeah, those rings look fine and the price is right. I guess I'm not so concerned about what's causing the expansion and if it is Star San there's nothing that can be done other than just frequently change them
Existing rings are from a mix of different replacement kits. Was making an effort to keep parts from different kits together but after having enough go bad I stopped trying to keep track of what came from what kit. I've frequently have them do this, this ring has expanded enough to effortlessly push it down out of the ring indention
