ABSTRACT:
A gasket (200) includes a metal substrate (202) that has a first opening (204) and a second opening (216) formed therein. A first sealing bead (208) substantially surrounds the first opening (204). A second sealing bead (220) substantially surrounds the second opening (216). A leak conduit (230) is formed in the metal substrate (202) in an area (228) between the first sealing bead (208) and the second sealing bead (220), such that a leak-flow (316) of a first fluid from the second opening (216) past the second sealing bead (220) is routed away from the first sealing bead (208).
