Patent ID: 7163238

Claim:
A flexible pipe and connector assembly, comprising: a) a connector body for coupling to the flexible pipe; b) said connector body including a frusto-conical portion and an adjacent cylindrical portion, said frusto-conical portion tapering from wide to narrow into the pipe; c) said frusto-conical portion having its widest portion adjacent said cylindrical portion and having a diameter greater than the diameter of said cylindrical portion and forming a radially extending substantially transverse shoulder with said cylindrical portion to force the pipe to form a bulge around said shoulder; d) said frusto-conical portion having its narrowest portion with a diameter slightly less than the inside diameter of the pipe thereby facilitating insertion of said frusto-conical portion into the pipe and e) a solid ring without radial holes, said ring having a cylindrical inner surface, the inside diameter of the ring being uniform and substantially equal to the outside diameter of the pipe, said cylindrical inner surface is positioned to overlie said cylindrical portion and said shoulder thereby to compress the bulge against said shoulder and seal the pipe to said connector body, the inside diameter of the ring remaining uniform after installation.
