Malleable iron fitting dimensions vary depending on the fitting type (elbow, tee, coupling, etc.), size (e.g., 1/2″, 1″, 2″), and pressure class (e.g., Class 150, Class 300). To find the exact dimensions, you must consult the Jizhong manufacturer’s technical data or specification sheets, which are often available as PDFs on Jizhong websites https://archpipes.com/news/company-blogs-en/malleable-iron-fittings-dimensions/
