Vibra-Lok Fittings Vibra-Lok Fittings

Parker’s Vibra-Lok Fittings provide a positive reliable seal under vibration conditions, mechanical shock or
tube movement. The sleeve cushions the tubing, permitting the tubing to flex back and forth in the fitting.
The seal design compensates for tube misalignment and tube surface defects.
