Great rings of color
These seal better than the stock o-rings, and the color coding is helpful. Wish all kegs came with Red and green colors on the post
ID Your Gas Line
I got these for all my gas posts, black for beer line - super easy to identify which is which when hooking up kegs. Blue ones are another alternative, but red just said 'GAS' to me. LOL Be sure to get some keg lube too.
This is the right O Ring
High quality O ring for your ball lock keg. Stop those leaks before they happen by replacing the o rings. Perfect fit and no leaks.
Love the color coding
Found that some of the o rings on my kegs couldn't hold the CO2 any longer. Replaced both in and out sides with color coded o rings making it quicker and easier to see what side is in and out. Not to mention the new o rings corrected my CO2 issues.
