A seal assembly (402) and methods of use, wherein the seal assembly (402) is formed of an elastomeric enclosure within which a primary cavity is defined. A second cavity in the form of a crushable container (214) is deployed within the primary chamber. An elastomeric compound is contained in one cavity and an elastomeric hardener contained in the other cavity. Upon application of an external force to the elastomeric enclosure, the enclosure is elastically deformed from a first shape to a second shape, wherein the second shape positions the elastomeric enclosure into a sealing configuration between adjacent annular surfaces. The external force also crushes the container (214), to cause mixing of the elastomeric compound and elastomeric hardener. Once the reaction is complete, the hardened compound retains the deformed shape of the elastomeric enclosure to maintain a seal between the annular surfaces. The most suitable drawing: Fig. 8.
