Keep your pressure cooker in top condition with the 20cm Sealing Ring. Securely fitting around the inside rim of the cover, the sealing ring forms a pressure-tight seal between the cover and the body of your pressure cooking during use. Choose to either fit them yourself or ask your local supplier to do the fitting for you. Before fitting, check your sealing ring is the right fit for your pressure cooker. Only use Tower sealing rings for your Tower pressure cooker. Compatible with 3L Pressure Cooker (T80245).
