I feel like this is a really dumb question, but I could use some help. I purchased two faucet shank kits from Amazon and the description calls out a 3/16" ID beer line connection.
However, when I measure across the barbed nipple, I measure 3/8". Logic tells me that I need to be ordering 3/8" ID beer line, but the reference on Amazon has me questioning myself. Maybe beer line is measured on the radius rather than diameter? Do I need 3/16" line or 3/8"? Help!
