Abstract
The subject invention provides a gasket for sealing multiple fluids and a method of forming the gasket. The gasket includes a carrier, a first elastomeric material, and a second elastomeric material different than the first elastomeric material. The first and second elastomeric materials are disposed in contact with the carrier in a flowable state such that the first and the second materials flow together to form a third elastomeric material comprising a mixture of the first and second elastomeric materials. The first and second elastomeric materials include cure systems that are compatible to ensure sufficient bonding within the third elastomeric material. Adhesive materials that are compatible with each of the first, second, and third elastomeric materials and the carrier are used to bond the elastomeric materials to the carrier.
