Abstract:
1. A tubular seal apparatus, comprising: a first tubular positioned coaxially with a second tubular having an annular space therebetween; a frustoconical portion at the first tubular, the frustoconical portion having a first end and a second end, such that a radial dimension of the annular space is larger at the first end of the frustoconical portion than a radial dimension of the annular space at the second end of the frustoconical portion; a tubular seal positioned within the annular space; and an urging member in operable communication with the tubular seal, the urging member being axially movable relative to the frustoconical portion such that movement of the urging member toward the second end of the frustoconical portion urges the tubular seal into sealing engagement with the frustoconical portion and causes diametrical deformation of the tubular seal to thereby sealingly engage with the second tubular, the urging member having a collet portion having longitudinal slots therein to allow diametrical deformation of the collet portion in response to the collet portion engaging the frustoconical portion.
