THE SCIENCE THAT STOPS CORROSION®
Each custom gasket solution is developed through direct collaboration with Av-DEC engineering teams and tailored to the customer application. Designs may include material selection, geometry optimization, and environmental testing to meet applicable FAA airworthiness requirements. When standard configurations are not sufficient, Av-DEC provides purpose-built gasket solutions that support fast installation, easy removal, and long-term protection.
EMI Closeout Panels require reliable electromagnetic shielding while maintaining precise mechanical integration within the aircraft or electronic enclosure. Designed to meet stringent fit tolerances and demanding EMI requirements while requiring wire harness feedthrough, this closeout solution helps complete the Faraday boundary by ensuring consistent surface contact across mating interfaces. Tight dimensional control eliminates gaps and discontinuities that can compromise shielding effectiveness, supporting dependable EMI containment in space constrained and performance critical applications.
By combining precision fit with proven EMI control principles, the EMI Faraday solution supports electrical continuity and predictable bonding performance at the final enclosure interface. The result is a robust closeout design that helps maintain system performance, reduce susceptibility to electromagnetic interference, and support long term reliability in high reliability aerospace and electronics environments.
BlackBox / LRU Sealing solutions are engineered to protect mission critical electronics by combining effective EMI shielding with durable environmental sealing. Designed for black boxes, LRUs, and other sensitive enclosures, these lid gaskets help maintain electromagnetic integrity at the enclosure interface while simultaneously sealing out moisture, fluids, and contaminants to meet todays new environmental requirements. By addressing both electrical and environmental threats in a single solution, they support reliable system performance in harsh operating environments.
Built to integrate seamlessly with enclosure and lid geometries, BlackBox / LRU sealing gaskets help ensure consistent compression and surface contact around the perimeter of the housing. This design approach supports predictable EMI performance while providing long term environmental protection that reduces corrosion risk and maintenance burden. The result is a robust sealing solution well suited for aerospace and defense applications where electronics protection, reliability, and compliance with EMI requirements are critical.
Av DEC provides custom gasket solutions for cabin entry door girt bars to help protect critical aircraft structure from corrosion in a highly exposed interface. Girt bar areas are subject to repeated environmental exposure, moisture intrusion, and mechanical loading, making them particularly vulnerable to long term corrosion if not properly sealed. Av DEC gaskets are engineered to conform precisely to the girt bar geometry, creating a durable environmental seal that minimizes moisture paths and helps preserve the surrounding structure.
Designed for reliability and ease of installation, Av DEC girt bar gasket solutions integrate seamlessly into both new installations and retrofit applications. The pre cured design provides consistent sealing performance without the variability or cleanup associated with form in place sealants, supporting repeatable results during maintenance events. By addressing corrosion risk at the girt bar interface, these solutions help extend structural life, reduce maintenance burden, and support long term aircraft durability.
Av DEC provides custom gasket solutions for aero shroud applications to help protect SATCOM antennas from water ingress and other environmental exposures. The aero shroud interface is a critical sealing boundary, where moisture intrusion, temperature differentials, and environmental contaminants can compromise antenna performance and surrounding structure if not properly managed. Av DEC gaskets are engineered to conform precisely to the shroud geometry, creating a consistent environmental seal that helps prevent moisture pathways into sensitive antenna assemblies.
Designed for long term durability and ease of installation, Av DEC aero shroud gasket solutions deliver repeatable sealing performance without the variability of form in place sealants. The pre cured design supports clean installation and removal during maintenance while maintaining reliable environmental protection over the service life of the aircraft. By protecting the SATCOM antenna installed in the aero shroud, these solutions help preserve system reliability, reduce corrosion risk, and support consistent aircraft communications performance.
