Abstract
A 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 flexible entry boot assembly comprises a seal member disposed within the containment region. A securing plate, disposed within the containment region, is releasably mounted to the seal member. A hollow support sleeve, integral with the seal member, extends axially into the containment region. The support sleeve has an outer surface and an inner, conduit receiving surface, and further has a degree of flexibility 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. The flexible boot assembly further comprises a mechanism for releasably attaching the hollow support sleeve to the conduit. A flexible, corrosion resistant sealing ring member is disposed outside the containment region. A mechanism, carried by the sealing ring member, is provided for releasably attaching the seal member to the wall of the containment region.
