Forcibly inserting it may cause streaks and deformation in the Teflon part, which may cause leakage.
To install the gasket, immerse it in hot water at 80°C for 10-15 seconds (increasing flexibility) and firmly insert the gasket diagonally along the streaks (including the filler part).
When purchasing a new product, gasket replacement can also be provided, so consult with the supplier.
