Keg Post O-Rings
Valuebrew carries two color schemes to color keg posts. Doing this allows you to quickly identify keg posts. Gray and Black match standard keg QD colors. Blue and Green are meant to be remembered by “Blue for Beer” and “Green for Gas”. All options are made from FDA rated silicone. Since they work equally well on gas and liquid posts you can also mix and match to come up with your own color coding standard.
What About Replacement Post Poppets?
Universal Poppets via Valuebrew
More InfoFrom the product description, check product page for current description, price and availability:
A Valuebrew Exclusive! Stainless Steel Universal Replacement Poppets with our Food Safe Silicone O-Rings.
These work with all standard Ball Lock and Pin Lock homebrew kegs.
Ever wonder what other universal poppet o-rings are made of? Us too, after all this is one of the most high contact o-rings in you draft beer setup. We took matters into our own hands and worked with our suppliers to source a 304 Stainless Steel + Food Grade Silicone option. Stainless steel construction on all the metal parts and premium quality food grade silicone for the o-ring.
Our pledge to you… Let’s face it, the stainless pieces in most universal replacement poppets should last a long, long time. How about the o-rings? Not so much… lost, broken, cracked, off smell. This is where our pledge comes in… we’ll always carry replacement o-rings for these universal poppets. No need to guess what size replacements to buy or completely replace your universal poppets because you don’t have a reliable source for replacements.
I use universal style poppets exclusively when rebuilding kegs. Finding the right OEM specific replacement poppets can be a chore. Beyond finding the right part number, these can be prohibitively expensive. Paying $10 to $14, or more, for an OEM poppet isn’t fun. In fact, if you really had to pay that, it may not even make sense to keep the keg.
I’ve long advocated to tossing OEM o-rings immediately. You don’t know what they’re made of, and you can’t get replacements. Replacing them immediately with a known quality o-ring and known part number before trimming to fit means you’ll be using the right materials and have a source for replacements. See: Universal Poppet Tips & Tricks
Well… finally there’s an option that comes with quality o-rings made from the right materials out of the box! Beyond that, Valuebrew has pledged to always carry replacement o-rings, so you’ll always have a source when the time comes for replacements. Available in 5 and 10 packs with the option to add on a pack of replacement o-rings.
More About Post Sizes and Compatible Tools
Ball Lock: There are two primary post sizes for standard ball lock kegs. 11/16″ and 7/8″. These can come in both 6 point and 12 point, compatible variations. For the larger 7/8″ posts I’ve seen both 6 point and 12 point styles. A 12 point socket will work on a 6 point post, but not vice versa. For the smaller 11/16″ posts I have only seen 6 point. Not to say that 12 point don’t exist, I just don’t recall seeing any. I have seen a couple other sizes – 5/8″ and 9/16″, but I would personally consider those more rare, and non-standard.
This is important from a tool perspective. I recommend a 12 point socket or wrench for larger 7/8″ posts. Smaller 11/16″ post should work with either 6 or 12 point tools.
Pin Lock: I’m aware of one standard size 13/16″. As previously mentioned this requires a special notched socket.
