Abstract
An environmentally-reactive seal for reducing fluid flow within a region to be sealed which moves from an installation orientation to a blocking orientation in response to predetermined environmental conditions. The seal includes a deformable first portion that is sensitive to environmental conditions and a cooperative second portion. The first portion moves from a first orientation to a second orientation when certain predetermined environmental conditions are exhibited, thereby urging the second portion into a sealing arrangement with seating points in the region to be sealed. A method for sealing a region using an environmentally-reactive seal is also disclosed.
