Abstract
A sealable enclosure including a base and a cover attachable to the base, the base and cover have respective mating surfaces, wherein the base and cover form a chamber there between when the cover is attached to the base. A compliant gel sealant is disposed on the mating surface of one of the base and cover for environmentally sealing the chamber, with a visual indicator provided for determining that the chamber is sealed. In one preferred embodiment, the visual indicator comprises a non-opaque window formed in the cover, and a non-opaque tongue extending from the mating surface of the cover, the tongue aligned with the window such that a line of sight is provided through the respective window and tongue. The gel sealant is disposed in a mating groove located about a perimeter of the mating surface of the base and substantially aligned with the tongue when the cover is attached to the base, such that a wetted contact between the gel and a distal end of the tongue, indicating that an environmental seal is formed there between, is visible through the line of sight.
