ABSTRACT:
Disclosed is a high pressure flow line connection. The connection includes a tubular male member, a tubular female member and a seal ring positioned between the male and female members. The male and female members have mating frusto-conical tapered surfaces, with the angle of taper of the female member being less than that of the male member. The seal ring has inner and outer tapered surfaces having angles of taper equal to those of the male and female members, respectively. The seal ring includes a radially outwardly extending lip adjacent the maximum outside diameter thereof. The male member, female member, and seal ring are cooperatively figured such that the seal ring lip remains spaced apart from the female member but optimum sealing engagement is achieved.
