Firewall Seals

Firewall seals made at Jonal typically are constructed from high temperature resistant silicone rubber, which can also be reinforced with flame resistant fabrics such as fiberglass, NOMEX and ceramic refractory cloth.

Firewall seals are used in jet engine applications as barriers to prevent the spread of flame in the event of a failure. These seals are typically designed to withstand direct flame at 2000 degrees F for 15 minutes per FAR requirements.
