The disclosed port device has a tubular inlet end stepped with progressively smaller land areas sized to establish a leakproof separable joint with outer land areas of conventional material mixing/dispensing tubes. Separate radial base blades hinged from the port device near its outlet end fit either unfolded flush against a flat surface aligned over a crack therein or back-folded into the crack itself, for alternative uses of the port device. The port device beyond the base is beveled across end edges, for cooperating with corner surfaces and guiding material discharge under pressure into an underlying corner crack, where two partly folded base blades can then fit flush against the corner surfaces. An expandable sleeve fitted into the structure crack can be deformed radially upon tightening a nut for retaining the port device in the structure even when dispensing material under high pressures into the crack, as by an accessory fitting mechanically locked to the port device. Another accessory fitting having interior and exterior stepped land areas sized the same as the material tubes and port device land areas, and the inner bore and exterior surfaces of conventional flexible hoses, provide for the remote interconnection of the material tube and port device via such hoses of virtually any length.

A port device for funneling material into a surface crack, comprising the combination of a tube having a throughbore between its inlet and outlet ends; the tube at the inlet end being stepped, as several adjacent generally cylindrical axially extended inner diameter land areas of progressively smaller diameters in moving downstream toward the outlet end, suited to correspond to at least one set of outer diameter land areas of conventional universally available material mixing/dispensing tubes, operable when the corresponding land areas are snugged together to establish a leakproof separable joint between the mixing/dispensing tube and the port device; the tube near the outlet end having a base comprised of separate radial blades circumferentially spaced around the tube and connected at circumferential hinge regions from the tube, the blades being shaped to have spaced apart side edges allowing the blades to be folded back against the tube without binding against one another, and the blades defining faces that lie when the blades are radial and unfolded along a plane generally normal to the tube; and the port device being alternatively suited to fit with the unfolded blade faces substantially flush against for bonding by adhesive to a flat surface with the tube throughbore aligned over the crack therein, or to fit with the back-folded blade faces defining a compact exterior into and be retained within a drilled somewhat cylindrical hole or a crack in the structure.
