A co-worker of mine had a roommate move out and leave his brewing stuff behind, including two 5 gallon kegs (pictured below). Co-worker ended up giving them to me for free.

Obviously you need a CO2 tank, and connectors, but what size CO2 tank and are the 'Ball Lock Connectors' the right one in general/these specific ones? Can I use the same cleaning/rinsing chemicals on these (PBW/StarSan)?

Since I am a complete noob to the world of using my own keg, what else do I need?

5 Gallon Kegs

Those are ball lock kegs. You can use PBW (or Oxiclean) to clean them and StarSan to sanitize. Common CO2 tank sizes are 5 gal. and 20 gal. 5 gal. are more portable if that matters to you. I use a 20 gal. and only need to get it filled once a year. Here is some excellent info on cleaning, maintaining, and using kegs....

    CO2 tanks are measured in lbs, not gallons. As you allude, the size of the tank does not matter other than how big it is / how long it will last between refills. – Hank Jun 26 '13 at 20:37
  • I have a 10# tank, it cost me about $20 more originally, but refills at my home brew store are $19 compared to $15 for a 5# tank. – Ugly Dude Jan 21 '14 at 17:13
  • A 5# tank is fine for serving at least 10 kegs, including purging of the kegs at least 3 times while racking beer into them. I also have had a slow leak completely deplete my recently filled tank. So I find that 5# tanks are a balance between occasional refills and the risk of losing all that gas due to a leak in the system. Another benefit is the 5# tank with regulator fits neatly in the kegerator where a 10# would not always... Lastly, I've taken it on a few outings since its easy to transport being a little 5# tank. So in conclusion I find 5# to be practical. – freshop Aug 15 '17 at 6:53

Good pictures and informative reading with no fluff

  • +1 on this article from Zymurgy. It's great and I refer to it often. The illustrations by Randy Mosher are nice too. – paul Jul 10 '13 at 19:41

  • The link worked for me just now. As an aside, Cornelius style kegs have a lot (a lot!) of seals and O-rings that can leak if they're not in perfect shape. Keg lube--food grade silicone grease--is a cheap way to make sure they stay that way. Most homebrew suppliers carry the stuff. – Glasseyed Aug 15 '17 at 19:24
