ABSTRACT:
A connector assembly 10 including a first member 16, 20 including a first fluid passageway 14, 18 therethrough and a female end portion having a conical surface 22, 58. A connector member 12 includes a second passageway 28 therethrough in fluid communication with the first passageway 14, 18 and a male end portion having a conical surface 30 in mating engagement with the conical surface 22, 58 of the female end portion. The connector member 12 is either directly threaded into the first member 16 or secured to the first member 20 by a nut member 36 to axially urge the conical surfaces 22, 30, 58 into mating engagement. The assembly 10 is characterized by the second passageway 28 within the male end portion of the connector member 12 having an increased diameter defining an annular recessed wall 38 which is outwardly radially deflectable in response to internal pressure applied against the recessed wall to perfect a seal between the conical surfaces 22, 30, 58.
