this is mine, it stays on 24/7 as long as it's plugged into a wall outlet...so it gives me peace of mind glancing at it every pour and at night, then in the morning....making sure it doesn't all the sudden lose 8ozs or some BS...

got the tip from someone else here a year ago, that kept their kegs on something similar...wish i could remember who, so i could give credit to the original idea man!

edit: works great for burst carbing too!

This is brilliant. Love this idea. Thanks for link!
 
I lost a 20 LBS tank overnight, I hope this thing fixes it. Taprite Retainer Screw for Permanent O-Ring


as coincidence would have it....just got reminded of an old thread, as i was remenising about things i've forgeten i said...this was the last post....and this part is what you need to screw into the tank, i believe, for a tap-rite o-ring to work...
 
I’ll see if I can locate the numbers. You can buy a lifetime’s worth of O-rings for minimal cost if you buy them bulk online. These are red silicone rubber rings, they are an upgrade from the buna rings usually used.

I totally agree with that! 50 cents for 1 O-ring vs. $4-6 for a 100 in bulk.

What makes them an upgrade? Silicone is very O2 permeable, much more so than Buna-N.
 
Agreed, silicone should be avoided on the cold side. As well, you cannot use silicone grease aka "keg lube" as it will slowly dissolve those O-rings leaving deposits inside QDs and given enough time make a QD difficult to remove from a keg post (bt/dt, all my keg posts now use Buna-N rings)...

Cheers!
 
I find a lot of the buna O-rings develop cracks prematurely causing early leakage. Not an issue with the silicone.

While I would agree that O2 permeability of silicone rubber tubing would be an issue, I’ve never experienced a problem using them as poppet O-rings. I change mine out each keg cleaning anyway, good practice for minimizing CO2 losses.

Again on the silicone lube, I’m changing it all out each cycle, never a problem dissolving a ring.

Most black rubber parts are produced in China, it seems the standards for black rubber items aren’t always there. The quality is all over the place, you never know what compounds they are using and a LOT of them crack prematurely. I got tired of finding cracked black O-rings and constantly refilling the CO2 tanks. Much improved with the silicone rings.
 
Are you talking about the o-ring that’s built into the regulator side? My tap-rite has those but I still use the nylon washer in addition to it. When I was first kegging I lost a whole tank pretty quickly. When I brought it to my welding supply shop to get it filled the guy immediately diagnosed the issue and gave me a couple of those nylon washers. After that, that wasn’t an issue; I’ve had other leaks but never from the tank post. I tape an extra to the backside of my regulator so I never lose one.
Thank you, yes, that is the o-ring I'm talking about. I tried the nylon washer in addition and it still leaks some. I have other regulators without the o-ring that do not leak with only the nylon washer. Pisses me of that some manufacturer would redesign something that works fine with a design that isn't reliable.
 
Sure.

Just, now I have to research all those grolsch style replacement washers I got off AMZ cuz I thought silicone would be so much better than questionable-unknown-rubberish-material washers from wherever.

Originally those red gaskets/washers were a flexible rubber product, they would dry out over a few years.

Right now I've only seen much harder, denser, plasticy, bright orangey-red ones.
I've had good success by flipping them over each time I clean the bottles, then store the empties open. Key being: the bale remains disengaged.
That way the gasket remains uncompressed, preventing the indentation, while it has time to relax the previous indentation on the opposite side somewhat.

When reused right away, the flatter side (due to flipping) will make a good new seal.
 
I had a batch of flat apfelwein due to those orange hard plastic ones on some far country sourced 750ml fliptops so I got these and have been happy. They say rubber.

I solved my lost co2 problem (I hope ) I went 100% silicone on my kegs, problem solved. Another pesky problem, the flat washer at the tank to regulator, tended to leak , I rubbed it on a medium diamond block and relieved the impressions, no more leak.

But you introduced another problem:
Silicone has a very high O2 permeability, which translates in oxidized beer over time.

Fix: Use EVA-Barrier tubing, instead! Also for your gas lines.
Bonus: 4mm ID will allow for much shorter beer lines, 4-6' is generally plenty at 12 psi.

I never knew this was an issue for any O-rings regardless of what material they are made from.
 
I use keg lube religiously. My O-rings are all black. They are new but black. so I assume some kinda non-silicone rubber.

the lid O-rings I use are white "silicone" as they were advertised to be. Have not noticed any O2 issues in my beers.
 
Silicone rubber is fine for O-rings, in fact I’ll say preferred IMHO. I’ve never noticed and O2 ingress whatsoever, for that matter the system is under CO2 pressure anyway.

All my leak issues went away when I switched to quality silicone, and away from buna-N from constantly changing sources. No more cracking O-rings leaking out your CO2.

what size are these? source?

I've never thought about the actual ring size or measured...just bought "keg O-rings" assuming various sellers already "size" them for kegs
 
For those using an 'extra' flat washer at the tank, do you still leave the rubber one that came with the TapRite regulator in? Long story short, I am on my 3rd new TapRite reg and when I close the tank and check valves I still slowly loose pressure on the high pressure side. Takes about 24 hours to drop 100PSI and I can't seem to fix it no matter what I do. I am trying an old flat washer I have from my previous reg, but maybe it needs replacing?

as far as i know, the nylon washers are only good for a couple uses....and do you have the reg good and tight to the tank?

edit: and yeah, i left the rubber one in.

I believe that for both nylon and fiber style, single-use is advised, but I would have no idea how many uses the gaskets in my numerous CO2, O2, and beergas regs have on them at this point - way more than one. I just check them for surface damage and toss if indicated. I don't have leaks.

Ironically, the very first refill on my dual-body Taprite reg I put tiny surface tears in the damn captive stem O-ring repositioning the gauge set by about 10° - dry.
Big mistake. Don't do that.

Cheers!
 
I was having this issue and my used kegs were the problem. The lids just weren’t closing tight enough and some of the posts would leak. It took a long time to get it sorted out but once I fixed the crappy kegs I stopped flying through CO2.
 
My captive o-ring on taprite developed a slight issue after I was moving it tank to tank for at-home vs at-tennis, 20lb vs 5lb. It was getting little "bits" of o-ring material squeezed out of the o-ring channel, to lie on the flat mating surface, and would cause leaking. I cleaned up the "bits" and it's fine. I also finally got another regulator to eliminate the swapping-induced wear and tear.

When you shut the tank valve, there's only a small amount of high pressure gas left inside the regulator. It could leak out through the high pressure side as well as the low pressure side.

Those little (low pressure) shut-off valves can be finicky. I had one that leaked through the stem when touched/jiggled, and replaced it. The regulator system holds pressure fine now, for weeks even.
 
Thanks for the replies. I'll source a new tank washer, crank the regulator on good and hope for the best. Getting frustrated by this one as I am sure it is at the regulator and hard to diagnose :(

Spray the connections with Starsan or bubble juice to check for leaks.

Contrary to common instructions (or habit), I actually do use a few turns of thin (white) teflon tape on the tank nozzle. It acts as a lubricant (not a seal). That way I can torque the (brass) regulator nut more easily and properly, without feeling the whole thing is gonna snap off. As the Germans would say "gutentight." ;)
