Flip Flop seals are a low-resistance, liquid-tight seal for use in a valve having a nozzle that telescopes into an axial fluid passage in a valve body.
The low resistance seal is designed to push open the valve controlling the flow of liquid into the filler head to prevent leaking from the filler bowl. The open/close action of the seal and the flexible design had led to the technical term “Flip Flop”.
The Better Drink Company found that the OEM seals were causing immediate leakage right after installation which worsened after time, causing the valves to not function properly leading to product wastage and additional time in sanitising.
To extend the life of flip flops seals which would increase the product yields and prevent wastage.
