Abstract
This invention relates to a sealed joint and a gasket therefor in which the gasket comprises a metal plate with an opening therethrough and with a sealing member of resilient material mounted on the metal plate within the opening and attached to the metal plate about a portion only of the periphery of the sealing member, the remaining portion of the periphery being unattached and preferably slightly spaced from the plate. The joint includes a pair of members to be sealed, one of the members having a central opening and also having another opening that is in register with an opening through the resilient sealing member. The members to be sealed have faces for clamping a thickened portion of the metal plate and also for sealingly contacting the resilient sealing member. The space between the plate and the unattached portion of the sealing member acts as a heat barrier to minimize transfer of heat emanating from the central opening from the plate to the sealing member.
