An annular elastomeric EMI shielding gasket includes a metallic mesh embedded in an elastomeric sheet for sealing and protecting aircraft fuel tanks and panels. In one embodiment, the gasket has a central region with a protruding portion to prevent leakage of fluid under the dynamic loading of the wing assembly experienced during flight. In another embodiment, the gasket has a rubberized tip portion providing the same advantages in an alternative configuration. In further embodiments, the annular inner section of the gasket includes a grommet bordering the gasket opening and encapsulating the inner most section of the gasket. In still further embodiments, the elastomeric sheet is formed from a fluorosilicate reinforced with Kevlar fibers, and the metallic mesh is formed from triple strand wire.
