If the Igloo coolers have a hole and spigot gasket that is larger than the Rubbermaid, then by all means just upsize to 1/2" parts instead. The general design should still be the same.
My whole purpose in using the 3/8" parts was that they fit the Rubbermaid spigot gasket PERFECTLY. If your parts fit a 1/2" gasket, then that will work too (in fact, some might prefer the larger hardware, albeit slightly more expensive).
