Flange is a crucial component identified by AN871-8D, constructed from aluminum alloy 6061. It features a nominal flange diameter of 1.750 inches and a thread class of 3B. The face seating surface is either ground or machined, ensuring a precise fit. The neck height is nominally 0.438 inches, designed for a tube outside diameter of 0.500 inches. With a thickness of 0.250 inches, this flange is ideal for applications requiring a plain face and welding neck style. The screw thread series is designated as UNF, and it has a round style with no bolt holes, making it suitable for various configurations.
