Patent ID: 7900967

Claim:
A dual-purpose component for an engine having an air intake manifold with an opening therein comprising: a fitting having: a body portion configured to fit within the opening and defining a passage having opposing first and second ends; a seal portion enclosing the first end of the passage; wherein the second end of the passage is open to the manifold when the body portion is fit within the manifold; a thinned wall joining the body portion and the seal portion establishing a predetermined fracture region at which the seal portion will separate from the body portion when sufficient torque is applied to the seal portion to thereby open the first end of the passage, the fitting thereby functioning as a seal when the seal portion is joined with the body portion, and functioning as a conduit when the seal portion is separated from the body portion; wherein the seal portion has a flange extending radially-outward adjacent the thinned wall and an annular ridge opposite the thinned wall from the flange; and wherein the flange defines a radially-extending surface for supporting a tool applied to the seal portion.
