This replacement silicone gasket is intended as a service part for Bionet pressure cookers. It helps maintain pressure in the pot, shorten cooking time, and ensure the lid works correctly—especially if the original gasket has hardened, cracked, absorbed odors, or if the cooker starts “hissing” during cooking and losing pressure.
Silicone is a flexible material that adapts well to the sealing surface. For proper compatibility, we recommend verifying the match with your specific pressure cooker model or the lid/gasket diameter.
