Av-DEC’s Hi-TAK Fuel Access Panel Gasket, with its “peel and stick” application method and its polyurethane sealant, offers many advantages over commonly-used grease-impregnated gaskets:  ease of use resulting in reduced installation time; no VOCs that evaporate over time and lead to voids that trap moisture which promotes corrosion; infinite shelf life when stored in original packaging and protected from UV exposure;  no use of grease, no need to degrease and reapply grease every five years, no greasy mess.  

The gasket’s aluminum mesh provides a conductive path for lightning strike protection over the life of the gasket and reduces fretting to the wing skin and door surfaces.  Its fuel-resistant polyurethane sealant fills voids and surface imperfections to protect the faying surfaces from moisture intrusion and corrosion, providing a long-term environmental seal.  The  flexible and cohesive nature of the gasket provides a high degree of environmental protection to help reduce or eliminate corrosion, reducing the scrap rate of tank access doors, decreasing cost and saving time, and improving the reliability of the air vehicle.
