Abstract
A ring gasket is retained 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, in some forms, at its outer periphery by a member connected to one of the connector parts between opposed abutting surfaces of the connector parts when they are connected. The ring gasket is increased in size, from a standard, to compensate for the standoff, so that the ring gasket is properly loaded. The support for the ring gasket, in another form, includes a direct connection between the ring gasket and the flange or support means, and in other forms, the ring gasket is supported at its inner periphery, and can not affect abutment between the flanges. The ring gasket has 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. The connection between the retaining means and the ring gasket permits such axial movement of the ring gasket as is necessary to enable loading thereof.
