Claim:
1. A sealing assembly comprising: an expansion band comprising: a pair of first threaded components having opposing threads and respectively captured within said pair of end portions, wherein a profile of each of said pair of end portions progressively radially thickens from a substantially rectangular cross-section starting at respective junctions between said arcuate band portion and said pair of end portions and advancing toward a substantially round cross-section at respective terminal end surfaces of said expansion band; and a second threaded component including oppositely-threaded ends respectively threadably engaged with said pair of first threaded components, such that rotation of said second threaded component in a first direction causes said pair of end portions to be simultaneously driven apart from one another to thereby expand a diameter of said arcuate band portion.
