A method and apparatus for installing seals in an interference fit with a comating sealing surface by initially stretching the seal (37) installed in a groove (15) to reduce its cross-sectional thickness perpendicular to a comating sealing surface (Fig. 4). The stretched seal (37) is mated with a comating surface and then relaxed, permitting the seal to return to an unstretched position (Fig. 3) and to passively assume a preloaded position against the comating sealing surface. The seal (37) may be repeatedly disengaged and reengaged by selectably restretching the seal (37) and then selectably releasing it upon completion of repositioning. |
