Hinged Flange Adapter allows a direct transition from flanged components to GRINNELL grooved components. The two segments design comes with a pre-pressed ring at one of the mating ends which facilitates a hinged action. This allows for an easy and quick installation. The specially designed gasket enables the transition from a grooved system to a flanged system with a single flange adapter. The flange bolt patterns conform to ANSI Class 125 and 150.
