Abstract
A double booted flexible entry boot provides a fluid-tight fitting between a wall of a fluid containment region and a conduit passing through the wall. An inner seal member is disposed within the containment region, the inner seal member having a substantially planar seal portion and an integral first hollow support sleeve concentric with the seal portion and extending axially into the containment region. A mechanism is provided for rigidifying the seal portion of the inner seal member. A mechanism releasably attaches the first hollow support sleeve to the conduit. An outer seal member is disposed outside of the containment region, the outer seal member having a substantially planar seal portion and an integral second hollow support sleeve concentric with the seal portion and extending axially away from the containment region. A mechanism is provided for rigidifying the seal portion of the outer seal member. The first and second support sleeves have a degree of flexibility sufficient to allow for the insertion of the conduit at angles not necessarily normal to the fluid containment wall. A mechanism releasably attaches the second hollow support sleeve to the conduit. A mechanism, c…
