Pressure Cooker Silicone Sealing Ring 18–32cm Universal O-Ring

Universal Silicone Sealing Ring for Aluminum Pressure Cookers

Keep your pressure cooker performing at its best with this food-grade silicone sealing ring. Designed as a direct replacement for worn or deformed gaskets, this O-ring creates an airtight seal to ensure safe, efficient cooking every time. Available in multiple sizes — A18, A20, A22, A24, A26, A28, A30, and A32 cm — to fit a wide range of aluminum alloy pressure cookers.

Why Replace Your Sealing Ring?

How to Choose the Right Size

The "A" size refers to the internal diameter of your pressure cooker (e.g., A22 = 22 cm internal diameter). Please measure your existing ring or the inner rim of your cooker before ordering to ensure the best fit. Note: Please allow a manual measurement deviation of approximately 1–3 cm.
