The containers we contact Ball Lock and Pin Lock Kegs come from the soda industry. Also referred to as Cornelius Kegs, Corny Kegs and Corney Kegs, they were originally designed to shop and distribute soda pre-mix. The big soda companies chosen various 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 important to comprehend each do the same with somewhat different and measurements and has. Note: All measurements in this post should be considered approximate. You will find different types and manufacturers of kegs. Their sizes are usually approximately the same, however, many kegs and producers differ slightly. There are several sizes of kegs readily available including 2.5, 3, 5, 10 and 15 gallons. This article targets the frequently used 5 gallon dimension.
The first thing you’ll notice is measurements – Pin Lock Kegs wider than Ball Lock kegs. Pin Hair will also be smaller than Ball Lock Kegs. Ball Lock on Left, Pin Lock on Right. Both these kegs have a ~5 gallon capacity.
Generally speaking… Each Ball Lock and Pin Lock design covers are similar measurement and they are interchangeable. You can make use of a Ball Lock Cover on a Pin Lock Keg and the other way around. A significant difference are the PRV (stress relief device) functions between the two styles. Both have automatic safety PRV valves. Which is, in the event the pressure gets excessive, both will automatically vent for safety factors. The difference is within manual PRV performance.
Ball Lock Keg lids use a pull diamond ring that allows you to personally vent the keg as you would like. You may want to do that with regards to taking out the keg cover or vent extra pressure in an attempt to get down to your lower stress. Possessing a manual PRV valve is definitely an advantage inside my book and on this count Ball Lock Style kegs win. Again, they are general statements, check using the keg’s manufacturer or distributor for specific keg cover dimensions and PRV performance. Note: There exists an additional more uncommon scale of lid/keg psssmu racetrack design. These are not exchangeable with standard lids.
Because regular Ball Lock and Pin Lock Lids are exchangeable. A great upgrade for Pin Lock kegs would be to change Pin Lock design covers with Ball Lock Design Lids. Ball Lock style covers are, for me, exceptional because the manual PRV allows you to effortlessly vent your keg when needed.
Ball Lock: The two main main post sizes for standard ball lock kegs. 11/16″ and 7/8″”. These can come in each 6 point and 12 point, compatible variations. For your bigger 7/8″” posts I have observed each 6 point and 12 point styles. A 12 point socket will work on a 6 point article, although not the other way round. For the smaller 11/16″” articles I actually have only observed 6 point. Not to say that 12 point do not really exist, I just don’t recall viewing any. I actually have observed a couple of other sizes – 5/8″” and 9/16″”, having said that i would personally think about those more uncommon, and non-regular.
This is important from a device point of view. I recommend a 12 point plug or wrench for larger 7/8″” posts. Smaller sized 11/16″” article ought to work with either 6 or 12 point resources. Pin Lock: I’m mindful of one standard dimension 13/16″. As previously mentioned this involves a unique notched plug.
