A firewall sealing assembly is provided for use between a firewall and a penetrating member. The assembly comprises a flexible coupling and a secondary seal. The flexible coupling is configured to provide a primary seal between the firewall and the penetrating member. The secondary seal is configured to provide a secondary seal between the firewall and the penetrating member. The secondary seal is positioned spaced apart from the flexible coupling to define a seal cavity there between.

What is claimed is: 1. A firewall sealing assembly for sealing between a firewall and a penetrating member comprising: a flexible coupling configured to provide a primary seal between the firewall and the penetrating member; a secondary seal configured to provide a secondary seal between the firewall and the penetrating member, the secondary seal configured in sealing engagement with the penetrating member, the secondary seal coupled to the flexible coupling and positioned spaced apart from the flexible coupling; and a seal cavity defined by the flexible coupling, the secondary seal and the penetrating member and configured to contain a backside flame generated on a backside of the flexible coupling. 2. A firewall sealing assembly as claimed in claim 1, wherein the flexible coupling is configured to backside burn upon exposure to a predetermined temperature. 3. A firewall sealing assembly as claimed in claim 1, wherein the secondary seal includes an outer radial wall, an inner radial wall, and an axial wall, the axial wall extending axially between the outer radial wall and the inner radial, the inner radial wall having an inner peripheral edge defining an opening through which the penetrating member may extend. 4. A firewall sealing assembly as claimed in claim 3, wherein the secondary seal is a conformable fire resistant washer. 5. A firewall sealing assembly as claimed in claim 1, wherein the flexible coupling and the secondary seal are comprised of a fireproof material. 6. A firewall sealing assembly as claimed in claim 5, wherein the flexible coupling comprises fiberglass reinforced silicone. 7. A firewall sealing assembly as claimed in claim 5, wherein the secondary seal comprises fiber reinforced plastic composite. 8. A firewall sealing assembly as claimed in claim 7, wherein the secondary seal comprises graphite-bismaleimide. 9. A firewall sealing assembly for sealing between a firewall and a penetrating member comprising: a flexible coupling configured to provide a primary seal between the firewall and the penetrating member; and a secondary seal configured to provide a secondary seal between the firewall and the penetrating member, the secondary seal having an outer and an inner radial wall and an axial wall, the axial wall extending axially between the outer radial wall and the inner radial wall, the inner radial wall having an inner peripheral edge defining an opening through which the penetrating member may extend, the inner peripheral edge configured in sealing engagement with the penetrating member, the secondary seal coupled to the flexible coupling and positioned spaced apart from the flexible coupling; a seal cavity formed there between the flexible coupling and the secondary seal, the seal cavity defined by the flexible coupling, the secondary seal and the penetrating member and configured to contain a backside flame generated on a backside of the flexible coupling. 10. A firewall sealing assembly as claimed in claim 9, further including an anti-friction plate configured to decrease friction between the flexible coupling and the secondary seal. 11. A firewall sealing assembly as claimed in claim 9, wherein the secondary seal is a conformable fire resistant washer. 12. A firewall sealing assembly as claimed in claim 9, wherein the flexible coupling is configured to backside burn upon exposure to a predetermined temperature. 13. A firewall sealing assembly as claimed in claim 9, wherein the flexible coupling and the secondary seal are comprised of a fireproof material. 14. A firewall sealing assembly as claimed in claim 13, wherein the flexible coupling comprises fiberglass reinforced silicone. 15. A firewall sealing assembly as claimed in claim 13, wherein the secondary seal comprises fiber reinforced plastic composite. 16. A firewall sealing assembly as claimed in claim 15, wherein the secondary seal comprises graphite-bismaleimide. 17. A firewall sealing assembly for sealing between a firewall and a penetrating member comprising: a sacrificial flexible coupling configured to provide a primary seal between the firewall and the penetrating member; a secondary seal configured to provide a secondary seal between the firewall and the penetrating member, the secondary seal having an outer and an inner radial wall and an axial wall coupled there between, the axial wall extending axially between the outer radial wall and the inner radial wall, the inner radial wall having an inner peripheral edge defining an opening through which the penetrating member may extend, the inner peripheral edge configured in sealing engagement with the penetrating member, the secondary seal positioned spaced apart from the flexible coupling; a seal cavity defined between the flexible coupling and the secondary seal, the seal cavity defined by the sacrificial flexible coupling, the secondary seal and the penetrating member and configured to contain a backside flame generated on a backside of the sacrificial flexible coupling; and an anti-friction plate disposed between the flexible coupling and the secondary seal to decrease friction there between. 18. A firewall sealing assembly as claimed in claim 17, wherein the secondary seal is a conformable fire resistant washer. 19. A firewall sealing assembly as claimed in claim 18, wherein the sacrificial flexible coupling and the secondary seal are comprised of a fireproof material. 20. A firewall sealing assembly as claimed in claim 19, wherein the sacrificial flexible coupling comprises fiberglass reinforced silicone and the secondary seal comprises fiber reinforced plastic composite.
