Abstract

A ducted flexible entry boot assembly provides a fluid-tight fitting between a wall of a fluid containment region and a conduit passing through the wall. The ducted flexible entry boot assembly comprises a seal member adapted to be disposed within the containment region, the seal member having a substantially planar seal portion and an integral hollow support sleeve concentric with the seal portion and adapted to extend axially into the containment region. The support sleeve has an outer surface and an inner, conduit receiving surface, and has a degree of flexibility relative to the seal portion sufficient to allow for the insertion of the conduit at angles equal to or other than an angle normal to the fluid containment wall while maintaining a fluid-tight environment. A mechanism is provided for rigidifying the seal portion of the seal member. The hollow support sleeve is releasably attached to the conduit. A flexible, corrosion resistant sealing ring member is adapted to be disposed outside the containment region. A flexibly rigid ducting boot is integrally formed with, and extends outwardly from the sealing ring member. A mechanism is provided for sealing the sealing ring member…
