This Parker Vibra-Lok Compression Style Fitting Nut 3/8″is engineered to provide a reliable seal in applications involving vibration, high heat, mechanical shock and tube movement. The sleeve cushions the tubing, permitting the tubing to flex back and forth in the fitting. The seal compensates for tube misalignment and tube surface defects. Flaring or belling the tubing before assembly doubles the working pressure of the Vibra-Lok fitting. Vibra-Lok fittings can be used in applications involving static pressure, minor surges or shock and severe vibrations or shock.
