ABSTRACT:
A ring gasket is retainer in position on a pipe connector flange with the ring gasket properly positioned for sealing engagement and loading between opposed circular grooves in the flange and a mating flange or member. The ring gasket is supported on one of the connector parts by a spacer ring or by a portion of the flange which effects a standoff between the connector parts when they are connected. The support for the ring gasket includes a flexible connection between the inside of the spacer ring and the outer periphery of the ring gasket. The ring gasket has outer peripheral, oppositely tapered sealing surfaces loaded into sealing engagement with opposing companion surfaces forming the grooves in the flanges upon making up of the connection, and the flexible connection between the spacer ring and the ring gasket permits such axial movement of the ring gasket as is necessary to enable loading thereof.
