ORIGINS OF THE PRESS FITTING To fully understand the innovative content of the new Series C4 it is necessary to analyze the theory of operation of the traditional Series 70….. often named the “Italian version”, which has been on the market for several decades without any substantial innovation. In the Series 70…. the mechanism of connection between the flexible tube, the fitting for the tube and the sleeve to crimp was basically split into two different parts faced separately: the fastening of the flexible tube and the seal of the fluid. In the external part the crimping of the sleeve (both skive...
