The Model SS-41 stainless steel flange adapter allows for a direct connection with ANSI Class 125/150 flanges. The specially designed gasket allows for the transition from a grooved system to a flanged system or component with a single flange. The SS-41 is investment cast in grades CF8 (304), CF8M (316) as well as the optional grades shown below. Integral closure tabs located on the flange O.D. help to facilitate alignment and assembly.
