Abstract
A penetration seal (12) is provided including a flexible patch (14) having adhesive (20) applied to one of the patch's first and second face surfaces (16), (18). An opening (22) is formed in the patch (14) of a size predetermined to fit a particular penetration (24). The opening (22) is slightly smaller than the cross-sectional shape of the penetration (24). In addition, a method of sealing the space (28) between an aircraft penetration (24) and surrounding insulation material (26) is provided. The method includes providing a seal (12) having a patch (14) with first and second face surfaces (16), (18), an opening (22) in the patch (14), and adhesive (20) applied to the first face surface (16). The method further includes applying the patch (14) to the penetration and insulation material by passing the penetration (24) through the opening (22) at the first face and pressing the first face surface (16) to the insulation material (26). In preferred embodiments, the method includes removing the seal (12) and the surrounding insulation material (26) as an assembly from the penetration and reapplying it at a later time.
