I have looked everywhere and can't find an answer to what I assume should be an easy question. I am building a jockey box using a 50' coil that is 3/8" OD. Do I need to buy a beer shank and coupler that has a 3/8" bore or can I use any bore size? It is fairly easy to find a coupler with a 3/8" bore, but almost impossible to find a beer shank with a 3/8" bore. I assume you want the bore size to be the same as the tubing size so the end of the coil can slide inside the bore to some extent. Am I overthinking this?
