Problems solved by technology

[0013] However, the shown fitting has the disadvantage that when the pipe is used in ACR applications (air conditioning and refrigeration applications), the connection force is not sufficient to ensure a reliable fastening of the pipe within the fitting
At these pressures, the joints known in the state of the art do not guarantee a sufficiently reliable and rigid connection between the joint and the pipe
