Patent ID: 8152204

Claim:
A fluid automotive high-pressure brake tube connector assembly comprising: (a) a connector body having an inner seat having a portion defining a concave frustoconical surface; (b) a generally cylindrical elongate brake tube constructed and arranged for use in automotive braking applications, the elongate brake tube having a flared end with an external abutment surface, and a passageway hole extending along a longitudinal axis of the elongate brake tube; and (c) a nut; wherein said connector body is adapted to receive said elongate brake tube and said nut to form a substantially rigid connection, and wherein said flared end of said elongate brake tube and said concave frustoconical surface of said inner seat are engaged so as to form a fluid seal between said connector body and said elongate brake tube; and wherein said external abutment surface has a sealing surface mating with said concave frustoconical surface of said inner seat of said connector body; and wherein said external abutment surface of said flared end has a borderline region between a lip area and the sealing surface, said lip area being situated between said sealing surface and said passageway hole, and the entire sealing surface being defined by at least part of a surface of a sphere, a center of said sphere being generally positioned along the longitudinal axis of said elongate brake tube and said sphere having a diameter greater than an outer diameter of the elongate brake tube.
