Abstract
An apparatus for connecting first and second tubular bodies comprising first and second flange assemblies, each of which has a hub and an annular flange in surrounding relationship to the hub, the hubs and flanges having engageable, complementary frustoconical surfaces that, when the first and second flange assemblies are subjected to compressive loading by means of threaded studs and nuts, cooperate to urge seal faces on the hubs into metal-to-metal sealing contact.
