The first and second layers have a plurality of first passageways that are sealed with a rupturable membrane to protect the sealant contained within the sealant chamber. The gasket has at least one second passageway to accommodate flow ways and fastener devices associated with two the opposing surfaces to be sealed with the aid of the gasket described herein.
