Abstract:
1. A coupling element, comprising: a male sealing element having a first end, second end, and a longitudinal axis extending between said first end and said second end, wherein said male sealing element has a generally cylindrical shape, wherein said male sealing element defines a fluid passageway therethrough for the transmission of fluid, wherein said male sealing element is slideably coupled to a ferrule, wherein said first end defines a conical sealing surface, wherein said conical sealing surface has a mismatched angle to a female sealing element, wherein said female sealing element defines a complementary conical geometry and said male conical surface extending beyond a proximal portion of said female element; and a biasing element disposed between a retaining ring and said ferrule located within a cavity in said female sealing element for biasing said first end into direct abutting contact with said female sealing element with a biasing force sufficient to form a fluid-tight seal between said first end and said female sealing element wherein said retaining ring assists in maintaining the integrity of said biasing element and said ferrule and said retaining ring provides a surface for said biasing element to be biased against when an axial force is applied.
