Once the perfect tube size was determined, the next hurdle was how to connect the track pieces together. This was a question of aesthetics, but also of function. A food grade track needs to have minimal horizontal surfaces, so that contaminants do not have a place to land, collect, or grow. Additionally, the connection point of one piece of tube track to another needs to be completely sealed for the same reason. It was determined that a combination of a custom designed internal connection, sealed with FDA grade silicone sealant, as well as a diagonally slanted external bracket would be the best connection method. These two connection methods, when used together, check all the boxes to keep the track securely fastened together and also completely FDA compliant.
