When it comes to kegerators, one of the most important components is the tubing. The tubing size plays a crucial role in determining the flow rate and resistance of the beer dispensing system, which ultimately affects the quality of the pour.
The common tubing size used in kegerators is 3/16 inch. This measurement refers to the inner diameter of the tubing, which is approximately 4.8mm. This size is widely used because it strikes a good balance between flow rate and resistance.
Using a tubing with a smaller diameter would result in higher resistance, which means that the beer would flow more slowly through the system. This could lead to a longer wait time for a pour and potentially more foam in the glass. On the other hand, using a tubing with a larger diameter would result in lower resistance, allowing the beer to flow more quickly. While this may seem desirable, it could also lead to excessive foam and a less controlled pour.
I have personally experienced the difference that tubing size can make in a kegerator. I once had a kegerator with a smaller diameter tubing, and I found that it took longer to pour a beer and there was often too much foam. After switching to a 3/16 inch tubing, I noticed a significant improvement in the pour quality. The beer flowed smoothly, with just the right amount of foam, and the wait time was reduced.
It is worth noting that while 3/16 inch is the most common tubing size for kegerators, there are other sizes available as well. For example, some commercial kegerators may use larger diameter tubing to accommodate higher flow rates. Additionally, there may be variations in tubing size depending on the specific beer dispensing system or the preferences of the brewer.
The common tubing size for kegerators is 3/16 inch. This size provides a good balance between flow rate and resistance, resulting in a smooth pour with minimal foam. However, it is important to consider the specific requirements of your beer dispensing system and adjust the tubing size accordingly.
