We work all over Ca. Many supply houses haven't stocked the
Raintight fittings until recently. We finally found a jurisdiction that is requiring them and are now eating the cost difference. It seems crazy that you have to use rainproof fittings on a sleeve or a conduit that ends with an open end like at a ground rod. I also envision conduits prematurely rotting from the inside in certain instances. But then again maybe I'm biased because I'm losing a chunk of change.
