Used & Pressure TestedBall LockWith Pressure Relief Valve(As of 2-17-2014 )(We are throwing in a set of O-rings with every purchase of this keg.)Pressure tested 5 gallon, stainless steel, corneliusstyle tank. These tanks are guaranteed to hold pressure. 22-23" tall and 9.5" 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 poppets that were installed when we received the tanks. We will often change an o-ring or poppet to get the tank to hold pressure. If you would like to have new o-rings or poppets, the options below allow you to add these. We do not change them but simply add them to the order. 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.If you are unhappy with your used 5 Gallon Cornelius Kegs for any reason, we will gladly take them back. The purchaser will be responsible for return shipping charges.
