The ferrule is enlarged and includes oversized fastener openings configured to allow circumferential alignment between the swivel flange and openings in a mating surface. The assembly also includes a gasket having openings, and the gasket is positioned between the ferrule and the mating surface so that a seal is formed between when the fasteners which extend through the flange, ferrule, gasket and mating surface openings are tightened.
