Abstract
Sealant nozzle (10) includes a positioning spider (18) at its outlet end. Spider (18) is inserted into a mounting hole (50), or is secured to an outer surface, or is mounted in a corner region (76, 78) of a structure (46). Spider (18) includes a plurality of radial lugs (22) which bend about flex hinges (34), enabling the spider (18) to automatically conform to a range of hole sues. In a surface installation, the lugs (22) are glued to the surface. In a corner installation, some of the lugs (22) contact and are glued to intersecting surfaces (76, 78) which define the corner. A sealant is delivered into and through a passageway (26) in the nozzle (10), to and through an enlarged diameter end cavity (24) at the outlet of passageway (26), and then into the crack to be sealed.
