ABSTRACT:
A new and improved seal for an overshot and method for doing same wherein the seal includes a seal ring body mounted with the overshot, the seal ring body having a first and second sealing lip formed therewith and extending inwardly into the bore of the overshot, with the first sealing lip for initially engaging the tubular member to reduce fluid flow therebetween and the second sealing lip, spaced above the first sealing lip, for establishing a fluid-tight relation between the second sealing lip and the tubular member for preventing fluid flow therebetween.
