Overview
There are two fireseals for the cowls, one each on the inboard edge of the lower and upper cowl. The fireseals are made from elastomer molding with reinforced fiberglass which seal the interface between the cowls and pylon fairings.
Each fireseal is installed on the Z-stiffener with spigots which are part of the molded rubber assembly. Each fireseal is bonded to the Z-stiffener with RTV732.
