A seal for a flexible alignment sealing coupling. The seal includes an annular member being symmetric about a longitudinal axis. The annular member has a radially inward facing surface extending an axial width between a first axial end and a second axial end. In a relaxed state of the seal, the radially inward facing surface has an asymmetric generally concave V-shaped cross section and is defined by a first section and a second section. The first section has a first seal taper angle measured relative to a line parallel to the longitudinal axis. The second section has a second seal taper angle measured relative to another line parallel to the longitudinal axis. The first seal taper angle is less than the second seal taper angle. Each of the first seal taper angle and the second seal taper angle is greater than zero degrees and less than 90 degrees.

A coupler assembly (10) and method of manufacture (10) for use with pipe comprising a unitary annular body (20) forming first and second cylindrical openings for surrounding a pipe or piping sections to facilitate forming a fluid-tight seal therein. The unitary annular body (20) comprises a medial portion (64) formed from a first material having a first durometer and first and second lateral portions (56, 58) integrally connected to opposite ends of the medial portion (64). The first and second lateral portions (56, 58) are made from a second material having a second durometer relatively higher than the first durometer of the first material. The coupler assembly (10) further comprises at least one clamping assembly (26) surrounding the unitary annular body member (20) adapted for compressing the coupler assembly (10) into a fluid-tight seal.

A routing support (64) for a conduit line fastened in openings and the line includes a plurality of conduits connected end-to-end along a longitudinal axis. The routing support (64) incorporates an outer body (66) with a structure (68) for fastening the body in an opening. The routing support also includes a housing structure to accommodate the ends of two conduits in an end-to-end arrangement and the structure may include two separate structures (one for each conduit end (72)) or a single common structure (accommodating respective ends of the two conduits). The routing support also includes a flexible interface (74) connecting the housing structure (70) to the outer body (66). In addition, the flexible interface (74) and the outer body (66) and the housing structure (70) are integral. Embodiments include a line for transporting fuel with this routing support, and an aircraft wing in which such a line/support transports fuel.

A coupling device for releasably connecting fluid-carrying duct ends of ducts is provided. The duct ends, respectively, each carry a jacket having at least two annular ribs housing a first annular sealing element. The first annular sealing element is engaged by the inner shell. The coupling device includes an outer shell that has radially inward extending ribs or rib portions, which are either arranged in an axial distance with respect to a further annular rib of the jackets or engage an axial recess provided on the jackets defined between the further annular rib and a fourth annular rib.
