ABSTRACT:
A pipe coupling includes a coupling body 50 and swage ring 52 for urging over the coupling body 50 in order to secure pipes 108 together. The coupling body 50 includes a first main sealing tooth 50 and a second outboard sealing tooth 56. The swage ring 52 includes a kickdown device 101 which restores a loading force between the first main sealing tooth 50 and the pipe 108, which loading force may have been reduced due to sequential tooth engagement and pipe radial deformation.
