Con-Aire Model Specs

I've checked on Starite's website, but can't find specifications on my current pressure tank. I would be great to have all the specs on it, but I'm really just looking for what size diamater the connection pipe is. I'm guessiing 1", but want to make sure.

It is a model CA 421-J.

Thanks.

You are correct. It has a 1" inlet/outlet.
