Get a Used Keg?… Replace Keg O-Rings

Replacing Keg O-Rings

When you get a used keg, in my opinion, you’re going to want to replace all the o-rings in your keg.  Generally speaking they are going to be worn out and even if they aren’t they’ll smell of soda pre-mix.  Beyond that, who knows what they’re made from.  Start with a clean slate.  As you saw earlier, the o-rings in this keg were a grubby mismatch of soda drenched o-rings.

Most of these o-rings are pennies each when bought in reasonable bulk quantities. It’s worth the small cost to start fresh with o-rings made from appropriate materials.

This write-up is part of my post on rebuilding kegsJump To This Section – If you look through the post you’ll see just how good the keg looks at the end.

Hands on Review: Torpedo 10 Gallon Ball Lock Homebrew Kegs!

Larger 10 and 15 gallon homebrew kegs have been very hard to find… for years.  There have been a couple sources, eBay was a best bet, but that was touch and go at best.  When you could find one, prices were… outrageous.  $300++ for a used 10 gallon keg would not be uncommon.  Again, that’s IF you could find one.

Great news homebrewers…. MoreBeer has introduced 10 and 15 gallon homebrew ball lock kegs via their Torpedo line of kegs and accessories.  These are BRAND NEW kegs that are (hopefully) readily available at a reasonable price.

Why a larger 10 or 15 gallon homebrew keg?

The first and most obvious answer is for large batch brewers.  If you brew 10 or 15 gallon batches, it sure would be nice to have a keg that fits your entire batch.  Even if you don’t brew 10 gallons, you may want to brew a couple 5 gallon batches of the same beer (much like professional brewers do) and keg it in a single keg.

A less obvious answer to the question is… to use as a fermenter.  Kegs are well-built stainless steel vessels that are pressure capable.  You can easily move them around and they are built to be bumped around a bit.  Using a keg opens up some really interesting possibilities…. fermenting under pressure with a Spunding Valve [See: Build a Spunding Valve! – How and Why], naturally carbonating in the fermenter/Krausening (again with the aid of a Spunding Valve), transferring under pressure, oxygen-free (or near oxygen-free) transfers, re-purposing expelled CO2 and more.

A third application is similar to the second… Use as a UniVessel.  Ferment and serve in the same vessel.  Save time and simplify your process.

Valuebrew has an exclusive color coded option for keg post o-rings.  Blue and Green.  These are sized for ball lock kegs (although there is a workaround for pin lock kegs, see pin lock section below).  You can use these however you’d like, but the idea is to color code you keg posts for easy identification.  They recommend Blue for Beer and Green for Gas.

What about after that? Of course, you could just keep using them until they break, they smell or look horrible or… until you lose a tank of CO2 due to an o-ring related leak.

Ball Lock Kegs – $45 Each + Free Ship Eligible

Used 5 Gallon Cornelius Style Ball Lock Kegs via Adventures in Homebrewing

More Info

From the product description, check product page for current description, price and availability:

Pressure tested 5 gallon, stainless steel, cornelius style tank. These tanks are guaranteed to hold pressure. 25″ tall and 8.5″ diameter. Tanks will show normal wear and tear. May have stickers on kegs. May also have syrup residue in tanks as we only dump them.

Kegs include the o-rings and poppits that were installed when we received the tanks. We will often change an o-ring or poppit to get the tank to hold pressure. If you would like to have new o-rings or poppits, the options below allow you to add these. We do not change them but simply add them to the order.

If you are just getting into kegging you will need a kegging setup to go with these kegs. We sell picnic tap systems, tower systems, and kegerator systems.

We know some homebrewers are more picky than others, so please keep in mind that these are USED kegs. Some of these kegs are probably 30 years old. Do not expect new kegs. If you are looking for new kegs, please check out our new kegs. We try and have quality kegs available at all times. With this said, they are going to show normal wear and tear. We try not to purchase from Pepsi or Coke to avoid heavily used kegs. We are not implying that our kegs are not quality…we just want to avoid any misunderstandings. Most of the kegs have black protective tops and bottoms, some are blue. We may have a few green, red or yellow tops. If you want a particular color, please indicate that at checkout time and we will try to accommodate you.


  • These are on sale for $45
  • Free shipping eligible!  Most kegs at AIH do not qualify for free shipping.  These ball locks DO qualify!
