Abstract
A segment of a fluid manifold includes a flexible thermal shield with an insulation space defined inboard of the thermal shield to provide thermal isolation from conditions external to the thermal shield. The thermal shield includes a helically corrugated metal tube having opposed first and second ends. An outer collar is threaded to an end of the helically corrugated metal tube. The outer collar includes a crimped portion and an uncrimped portion. The uncrimped portion is spaced apart from the corrugated helical metal tube more than the crimped portion to define a vent between the outer collar and the corrugated helical metal tube in venting communication with the insulation space to vent hot gases.
