So, I have trouble with my pin lock kegs leaking co2 from the disconnects. I dont have this issue with my ball lock kegs. Can I just switch the posts out? Or are there different sizes?
Thanks!
Thanks!
I would first check the o-rings on the posts if you are having a leak when the disconnect is attached. That is almost always the issue. If it is leaking without the disconnects attached, then it is either the o-ring under the post or the poppet itself. I hope this helps!
Otherwise here is a good guide for thread sizes and whatnot:
Use a pure silicone grease. Petroleum products can eat the rubber o-rings. The silicone is also still slippery when cold.vasoline or keg lube? and i've had mixed luck with cheap replacement o-rings.....

Vasoline from a food safety standpoint should be safe enough, but it is a name brand for petroleum jelly. Similar to Kleenex is a brand of facial tissues.i've been using vasoline, is that what keg lube is? (my o-rings usually still last a few years)

Following that link, this is what's specced out in the right side column as well as under "description:"I do really like the silicone stuff mainly because a tiny film of it leaves the poppets slick for a long time, and it doesn't stiffen up in the cold keezer. This stuff, available in many brands

The half ounce might be lifetime supply.
I remember a discussion a while back on some forum or other about that confusing side bar description. The part about "petroleum based" is in error. These products contain no petroleum as can be confirmed by looking at the package or other sites' descriptions. Surprised Lowes website hasn't fixed that yet as it's been a couple of years. FWIW mine comes from the neighborhood Ace, but I bet all the brands are of a single manufacture with differnt labels.Following that link, this is what's specced out in the right side column as well as under "description:"

- Petroleum oil-based valve and faucet stem grease
- Waterproof and prevents corrosion
- Non-melting and non-hazardous
It also mentions on the label: 90% Pure Silicone
I have one of those containers for faucet cartridge lubrication and some other uses around the house, it's definitely not vaseline. Much thinner, slicker or "oilier" so to speak.
Never used it for kegging though.
It does look and feel like a better product for keg o-rings, and especially the poppets. Never occurred to me to use it for that!I do really like the silicone stuff mainly because a tiny film of it leaves the poppets slick for a long time, and it doesn't stiffen up in the cold keezer.
vaseline
It's unlikely they are the culprit, but possible if they're damaged, worn out, or leaky. They're easy to test in a small bucket with Starsan, connected to the gas with 10-20 psi pressure on it. The little screw lid in the top has a flat rubber o-ring/seal. If that's distorted or missing, it will not seal, and you should see the bubbling. If they pass the test, they should be fine to use.I'm starting to think it's my disconnacts. Are there different qualities of these pinlock disconnects? They all look the same to me.
I just replaced the o rings on the posts, which is why I think I might have some faulty disconnects.It's unlikely they are the culprit, but possible if they're damaged, worn out, or leaky.

Once the QD is on the keg's post, the rubber o-ring on top of the post is the only seal that matters. Poppets are immaterial, both are halfway opened due to equalized spring pressure, to allow passage of gas or liquid.
I have on at least one occasion mangled the internal o-ring in a QD when screwing the top back in after cleaning. Check them for crimping or other damage. They are cheaper than dirt to replace if this is the issue.I just replaced the o rings on the posts, which is why I think I might have some faulty disconnects.
I feel super dumb now. I never realized to you take them apart and fix that. I'll check that out. Thanks.I have on at least one occasion mangled the internal o-ring in a QD when screwing the top back in after cleaning. Check them for crimping or other damage.
