The containers we contact Ball Lock and Pin Lock Kegs come from the soda business. Also known as Cornelius Kegs, Corny Kegs and Corney Kegs, they were initially intended to store and distribute soft drinks pre-mix. The big soda companies decided on different style containers for their pre-blend. Pepsi landed on the Ball Lock style while Coke utilizes the Pin Lock style.
Homebrewers have because re-purposed these as homebrew dark beer kegs.
First, It’s vital that you understand each do the same thing with somewhat different and dimensions and has. Note: All measurements in this article should be considered approximate. There are different models and producers of kegs. Their sizes are usually about the same, but some kegs and manufacturers differ somewhat. There are many sizes of kegs readily available including 2.5, 3, 5, 10 and 15 gallons. This post concentrates on the commonly used 5 gallon dimension.
One thing you will observe is dimensions – Pin Lock Kegs wider than Ball Lock kegs. Pin Hair can also be shorter than Ball Lock Kegs. Ball Lock on Left, Pin Lock on Right. These two kegs use a ~5 gallon capacity.
Typically speaking… Each Ball Lock and Pin Lock style lids are identical dimension and therefore are exchangeable. You can make use of a Ball Lock Cover on the Pin Lock Keg and the other way around. A big difference are definitely the PRV (pressure relief device) features between the two styles. Have automatic safety PRV valves. Which is, if the stress gets excessive, each will instantly vent for safety factors. The difference is at handbook PRV functionality.
Ball Lock Keg covers possess a draw ring that allows you to manually vent the keg as you would like. You may wish to accomplish that just for eliminating the keg cover or to vent extra pressure in an attempt to get down to a lower stress. Possessing a handbook PRV valve is an advantage within my book as well as on this count Ball Lock Style kegs win. Once again, these are general statements, check using the keg’s manufacturer or supplier for particular keg cover measurements and PRV functionality. Note: There is certainly an additional more uncommon scale of lid/keg psssmu racetrack style. These are not exchangeable with regular covers.
Because regular Ball Lock and Pin Lock Lids are exchangeable. An excellent upgrade for Pin Lock kegs is to change Pin Lock style covers with Ball Lock Design Lids. Ball Lock design lids are, in my view, exceptional as the handbook PRV enables you to effortlessly vent your keg when needed.
Ball Lock: There are two main post sizes for standard ball lock kegs. 11/16″ and 7/8″”. These can come in each 6 point and 12 point, compatible variants. For the bigger 7/8″” articles I’ve observed each 6 point and 12 point designs. A 12 point plug will work over a 6 point post, however, not the other way around. For your smaller 11/16″” posts I have only observed 6 point. Not saying that 12 point do not exist, I just don’t recall seeing any. I have observed a couple of other sizes – 5/8″” and 9/16″”, however i would personally think about these much more rare, and non-standard.
This will be significant from a device point of view. I would recommend a 12 point plug or wrench for larger 7/8″” posts. Smaller 11/16″” article ought to work with either 6 or 12 point tools. Pin Lock: I am aware of one standard size 13/16″. As earlier mentioned this involves a unique notched plug.
