The Zavor Silicone Gasket is meant to help maintain the cooking performance of your Zavor Electric Cooker. This replacement gasket seals in pressure buildup to ensure food is cooked quickly and safely. The silicone gasket is placed on the inside edge of the pressure cooker lid to create a tight seal between the lid and the base to effectively seal in pressure. Keep your Zavor Electric Cooker up to date for best results!
