Kit contains a seal for one entry door, instructions and seal lube.


Nearly a year of development and testing went into creating this revolutionary new sealing material. This new seal for General Aviation Aircraft is the result of a space age material developed for NASA. It is ideal for airplanes because it conforms to the sealing surfaces, forming a perfect sealing bond between the door and the fuselage. Custom extruded from a special hybrid rubber compound, the new seal is superior to any seal on the market.

The hybrid rubber compound sealing material is unique because it compresses under pressure from the door. When the door stops applying pressure against the seal, the seal no longer compresses and actually makes an impression of the surface pressing against it. This seal conforms to surfaces so well that when you open the door you will actually see a perfect imprint in the seal of every rivet and seam!

The seal has the ability to compress from its full thickness to as small as 1/32" thick without losing its sealing ability.  The hybrid compound meets Military Specifications (Mil Spec). The seals are affordable and Made in the USA. The new seals are available at a fraction of the cost of OEM seals and benefits of their use include an airtight and water tight fit, and greatly reduced cabin noise for even more enjoyable flying!
