Abstract
The securing and sealing of a connector 10 to a pipe 12 for a hydraulic connection comprises a pre-assembly step wherein a cutting/clamping ring 34 is secured to the pipe and a final assembly step wherein the ring 34 is sealed to a connector body 14. The axial force applied by a nut 20 to the ring 34 during the final assembly step is less than the axial force applied to the ring 34 during the pre-assembly step whereby no further cutting of the teeth 40 into the pipe is permitted but sealing takes place between cooperating conical surfaces 22 and 36 of the connector body and cutting/clamping ring respectively.
