    Abstract: The fluid coupling assembly for retaining a sealed joint includes the first member adapted to be connected to a first fluid conduit with a per sealing surface and a series of axially aligned serrations along with helical threads. A second member of a complementary configuration is adapted to be connected to a second fluid conduit with complementary threads and an axially extending cylindrical collar with spaced axial notches forming cantilevered beams. Each of the cantilevered beams can have teeth capable of engaging a series of serrations to provide an appropriate resistant force for both sealing engagement and disengagement. The teeth and serrations can remain in contact to provide a visual determination of a pretorqued force between the first member and the second member.

    Abstract: An expanding panel fastener assembly (12) for affixing a honeycomb panel structure (2) to a support structure (4) is disclosing having an insert member (6) that attaches to a hole (8) drilled within the honeycomb panel (2). A flexible sleeve and retainer assembly (12) includes a molded flexible sleeve (34), an expander member (38) and a retainer member (36). A sleeve spacer (32) can further be attached to the flexible sleeve (34) to assist in retaining it within the insert member. By providing a fastener (14) for engagement with the retainer member (36), the expander member (38) can further prevent withdrawal of the retainer member and can further assist in expanding the flexible sleeve to provide a sealing configuration with any support structure.
