ABSTRACT:
A tubing inside an aircraft fuel tank is encircled by a dielectric support and wear sleeve that is comprised of two members that are clamped together circumferentially around the tubing. The members include projecting portions having an adhesive applied thereto along mating surfaces to rigidly couple the support sleeve members to each other. The mating surface is a circumferential arc that provides complete overlap of a portion of the two support sleeve members. The adhesive extends circumferentially along the mating surface to provide sufficient dielectric strength due to the extended length of the adhesive coupling. The tubing and sleeve are supported by a support assembly including a clamp, bracket and tank wall. The sleeve material has the necessary thickness and length to provide dielectric isolation of the tube from the support assembly. The sleeve is designed having tight tolerances along the outside diameter to permit axial motion with respect to the clamp while restraining radial motion. The sleeve may be easily removed and replaced without disturbing the tubing or other aircraft structure if desired.
