ABSTRACT:
An aircraft engine firewall seal includes a plurality of discrete, stacked-together sealing disks each have a central hole sized for receiving a feed-through member therethrough, with the disks being larger in outer diameter than the firewall aperture through which the feed-through member extends, and with the central holes being smaller in inner diameter than the firewall aperture. The disks are retained against the firewall by a retainer which fixedly clamps together the disks around the feed-through member for sealing gas flow through the firewall aperture.
