Product Description: A cooker rubber gasket is a circular seal that is placed between the lid and the base of a pressure cooker. It is made of rubber and is designed to create an airtight seal that prevents the release of steam and pressure during cooking. This allows the pressure cooker to build pressure and cook food quickly and efficiently.

The rubber gasket is typically easy to install and remove, and can be cleaned with a damp cloth or mild soap. It is important to regularly check the gasket for wear and tear, and replace it if it becomes damaged or worn. A worn or damaged gasket can cause the pressure cooker to lose pressure and may also cause leaks, which can be dangerous.

It's recommended to check the gasket before every use and replace it if it appears to be damaged or worn. Many pressure cooker manufacturers recommend replacing the gasket every 12 to 18 months, or as needed. Proper care and maintenance of the rubber gasket can help ensure the safe and efficient operation of the pressure cooker.
