ABSTRACT:
A compressible gasket is provided which has at least one bolt area with a tapered densification. The tapered densification puts the lowest porosity at a center area of the bolt area. The center area is that part of the bolt area which surrounds and abuts the bolt aperture itself, and in use is covered by the bolt head. Two embodiments are provided. In one the gasket will have a substantially uniform porosity throughout the center area underneath the bolt head. In the more preferred embodiment, the densification gradually decreases in a porosity gradient beginning at the aperture and going through the center area.
