Inquiry (采购产品): Female NPT Threaded Flanges Hi. I'm looking for Female NPT Threaded Flanges with a size of 3/8 inch for the pipe, and anywhere from 2.5 to 3 inches as a diameter of the whole piece. I would prefer aluminum or plastic but will take steel if I have no other choice. Do you have anything like that? If so how much do they cost for 4 of them? Thanks. **** Hidden Message ***** Aimee Chitayat CA 94706 USA Company: None E-mail: achitayat@hotmail.com **** Hidden Message ***** achitayat@hotmail.com
