1 in. Black Malleable Iron Threaded Floor Flange ...will this flange ( # 521-605HN ) work with black steel pipe • # 585-1200HC

Asked by: Thomas
This answer is very delayed, but for future reference, yes it does. It fits any pipe with an inside diameter of 1 inch. I've personally used this flange and the 585-1200HC and it fits securely, though it gets a little tight as you move up the threads.
