Abstract: A joint for a pipe having a flared end portion comprises (i) an inner tube portion adapted to be fitted into an inner circumference of the pipe; (ii) a joint body having a circular sealing surface extending from the inner tube portion, wherein the sealing surface is adapted to support the flared end portion of the pipe; and (iii) a securing component adapted to have the pipe inserted therethrough and to fixedly press the flared end portion against the sealing surface of the joint body, wherein the flared end portion is interposed between the sealing surface and the securing component.

Abstract: A pipe joint connecting a pipe using an anaerobic adhesive, which possesses a double pipe structure formed with an inner pipe fitting into the inner circumference side of the end of the pipe, and an outer pipe fitting into the outer circumference side of the end of the pipe, integrated with a gap between them, and a tapered surface formed with at least one or the other of the inner piper or outer pipe approaching the other; and a pleated O-ring provided on the end of the outer pipe to set the pipe in place by tightening an O-ring locking material supported by the outer pipe.
