A Cornelius keg or Corny keg is a type of keg originally manufactured by the Cornelius company for use in the soda industry. Now obsolete, they are easy to find used and popular with home brewers. These kegs are generally preferred by home brewers because they are well suited for storage in converted refrigerator or freezer kegerators and hold the typical 5 gallon batch of beer. These kegs can be found in used condition (often filled with residual CO2 pressure and a bit of old syrup) for a few dollars more than their worth in stainless steel scrap. 2 and 3 gallon versions are also available, although they are rarer than full-sized 5-gallon kegs.
Two different disconnect/coupling systems (ball-lock and pin-lock) were widely used and are NOT interchangable. The ball lock style is most commonly used by homebrewers and, unless stated, all information here is for ball lock kegs. There were three primary manufacturers of these kegs; Firestone, Cornelius, and John Wood. have a look at thesixtyone. net is actually MEANS superior to 50 % of these websites.

 Reconditioning Cornelius Kegs
At a minimum, all 5 O-rings should be replaced and the kegs should be filled with hot water/detergent over night (followed by sanitizer) before the first use.
