The containers we call Ball Lock and Pin Lock Kegs come from the soda industry. Also called Cornelius Kegs, Corny Kegs and Corney Kegs, they were originally intended to store and disperse soda pre-mix. The big soda companies selected different design containers for their pre-mix. Pepsi landed on the Ball Lock style whilst Coke uses the Pin Lock style.
Homebrewers have because re-purposed these as homebrew beer kegs.
First, It’s vital that you comprehend both do exactly the same thing with somewhat various and measurements and features. Note: All dimensions in this post is highly recommended estimated. There are different types and manufacturers of kegs. Their sizes are generally approximately the same, but some kegs and producers differ slightly. There are several sizes of kegs available including 2.5, 3, 5, 10 and 15 gallons. This article targets the widely used 5 gallon size.
The first thing you’ll observe is measurements – Pin Lock Kegs broader than Ball Lock kegs. Pin Hair are also smaller than Ball Lock Kegs. Ball Lock on Left, Pin Lock on Right. Both these kegs use a ~5 gallon capability.
Generally speaking… Each Ball Lock and Pin Lock style covers are the same dimension and they are exchangeable. You can make use of a Ball Lock Lid over a Pin Lock Keg and the other way round. A significant difference are the PRV (pressure relief valve) functions in between the two styles. Both have automatic safety PRV valves. That is certainly, in the event the stress becomes excessive, both will automatically vent for safety factors. The difference is at handbook PRV functionality.
Ball Lock Keg covers use a draw diamond ring that permits you to manually vent the keg as you would like. You may wish to accomplish that just for taking out the keg cover or vent extra stress so as to get down to some lower pressure. Having a handbook PRV valve is surely an advantage inside my book as well as on this count Ball Lock Design kegs win. Once again, these are general statements, check using the keg’s manufacturer or supplier for specific keg lid dimensions and PRV functionality. Note: There is another more uncommon scale of cover/keg psssmu racetrack design. These usually are not exchangeable with regular lids.
Since regular Ball Lock and Pin Lock Covers are interchangeable. An excellent upgrade for Pin Lock kegs is to change Pin Lock style lids with Ball Lock Design Lids. Ball Lock style lids are, in my view, superior since the handbook PRV allows you to effortlessly vent your keg as needed.
Ball Lock: There are 2 main article sizes for regular ball lock kegs. 11/16″ and 7/8″”. These can can be found in each 6 point and 12 point, compatible variants. For that bigger 7/8″” articles I have observed both 6 point and 12 point styles. A 12 point plug will work on a 6 point post, but not the other way round. For your smaller sized 11/16″” posts We have only observed 6 point. Not saying that 12 point don’t really exist, I just do not recall seeing any. We have seen a few other sizes – 5/8″” and 9/16″”, but I would personally consider these more rare, and non-regular.
This will be significant from the tool point of view. I would recommend a 12 point socket or wrench for larger 7/8″” articles. Smaller sized 11/16″” article ought to work with either 6 or 12 point tools. Pin Lock: I’m aware of one standard dimension 13/16″. As previously mentioned this calls for a special notched plug.
