ABSTRACT:
An applicator tip structure and method for applying a flexible sealant material on and around the heads of fasteners and on and around the surface surrounding the fastener head to prevent fluid passage between the fastener and the materials through which the fastener passes. The applicator tip has an outlet opening that is greater than the diameter of the sealant passageway in the applicator tip and that also is greater than the largest transverse dimension of the fastener, to provide an overlap area around the fastener head. In use the applicator tip is applied over the fastener head and is pressed into the surrounding surface around the fastener head to define an enclosure around the fastener head, into which enclosure the sealant material is injected to completely surround the fastener head and the adjacent surface to completely seal the fastener from fluid passage therearound.
