1. Product Overview
The Zerodis Silicone Sealing Ring is a high-quality replacement gasket designed for latching-type pressure cookers. Made from premium food-grade silicone, this sealing ring ensures a safe and effective seal for your cooking needs. It is engineered to withstand extreme temperatures and maintain its integrity through various cooking methods, including pressure cooking, steaming, and slow cooking.
This product is intended to replace worn-out or damaged sealing rings, restoring your pressure cooker's optimal performance and ensuring a leak-proof operation.
2. Setup and Compatibility
2.1 Verifying Compatibility
Before installing, it is crucial to verify the inner diameter of your pressure cooker. This sealing ring is specifically designed for pressure cookers with an inner diameter of 30cm (11.8 inches). Incorrect sizing can lead to steam leakage and unsafe operation.

2.2 Installation Instructions
- Remove Old Gasket: Carefully remove the old or damaged sealing ring from the pressure cooker lid.
- Clean Lid Groove: Ensure the groove on the pressure cooker lid where the gasket sits is clean and free from any food debris or residue.
- Insert New Gasket: Place the new Zerodis silicone sealing ring into the groove on the underside of the pressure cooker lid. Ensure the dual-edge groove design is properly seated and locks securely under the pressure cooker's wire rim.
- Check Fit: Gently press the ring into place around the entire circumference of the lid. It should sit snugly without any twists or gaps.

3. Operating Instructions
Once the sealing ring is correctly installed, it will create an airtight seal when the pressure cooker lid is closed and locked. This seal is essential for building and maintaining the necessary pressure for cooking.
- Always ensure the sealing ring is clean and properly seated before each use.
- Close the pressure cooker lid according to your cooker's manufacturer instructions, ensuring it is securely locked.
- The silicone ring will expand slightly under heat and pressure, enhancing the seal and preventing steam leakage.
4. Maintenance
Proper maintenance extends the life of your silicone sealing ring and ensures continued safe operation of your pressure cooker.
- Cleaning: The silicone sealing ring is completely dishwasher safe for convenient cleaning. For manual cleaning, wash with warm soapy water and rinse thoroughly.
- Sanitation: For thorough sanitation, you can boil the ring in water without damaging its structure or performance capabilities.
- Odor and Stain Resistance: The smooth silicone surface resists odor absorption and staining, but regular cleaning is recommended.
- Storage: Store the sealing ring flat or in its natural shape to prevent deformation when not in use.
5. Troubleshooting
If you experience issues with your pressure cooker after replacing the sealing ring, consider the following:
- Steam Leakage: If steam is escaping from around the lid, the sealing ring may not be properly seated, or its size might be incorrect for your pressure cooker.
- Incorrect Fit: If the ring appears too large or too small, double-check the inner diameter measurement of your pressure cooker against the product specifications. Even slight discrepancies can affect the seal.
- Deformation: Over time, or if stored improperly, the ring might deform. Replace the ring if it shows signs of permanent deformation or damage.
Always refer to your pressure cooker's original instruction manual for specific guidance on lid closure and safety.
