PURPOSE:To secure a piping joint in which piping to be connected to a connector body produces no dislocation in the both axial and radial directions even in a vibro-atmosphere. CONSTITUTION:In order to press the outer circumferential surface of piping P at the side of and end part, a projection 1a is installed in an inner circumferential surface of a connector body 1, and likewise a ring bush 27 providing another projection 27a on this inner circumferential surface is set up in an interval between the piping P and the connector body 1. Therefor even if being used in a vibro-atmosphere, the piping P will not be dislocated in both axial and radial directions, so such a fear that a seal ring is worn out and airtightness goes down is preventable. |
