The new seals are a departure from the weather stripping commonly used to seal the windows on Cessna aircraft. The new seal will install in the same location as the original weather stripping (on the door frame window opening), but unlike the foam rubber weather stripping, the new seal will conform and mold itself to the window frame regardless of how well or how badly the window fits. The new rubber compound has the capacity to sense the pressure from the closed window and can withdraw to as small as 1/16th of an inch. This will provide you with an air and water-tight seal like no other seal on the market. Never before could you appreciate how quiet your cabin can be. The seal is easy to install (with it’s own pressure sensitive adhesive strip) and is FAA-PMA approved for all Cessna aircraft.
