Can you tell us what size the fittings are, the type of cast iron and the application of the fittings (are you working to a particular code or spec)?
The material is A 126 cast iron (or so I'm told) I do not know the application. Most likely for a pumps and of a more than 8 to 10 inch size. Thanks everybody for the help thus far. I'd love to get a few more options to help gauge range of costs.
