Pressure compensating seal |
摘要 |
A seal for use between the edge of a housing opening and a cover attached to the opening has an outer gasket portion that substantially blocks the seam between the cover and the housing opening and edge, and an inner expandable and contractible portion that compensates for potential pressure differentials, thereby preventing ambient air from being drawn in through the seam.
