Sealing Ring And Overpressure 09901

This is a genuine Presto replacement part, it is sold individually. The purpose of the 09901 Pressure Cooker Sealing Ring/Automatic Air Vent Pack (6 Quart) is two-fold. The sealing ring is used to create a seal between the Pressure cooker lid and the pressure cooker pot. In the event if the pressure regulator fails, and to much pressure builds up in the pot, the Overpressure Plug will pop out of the lid releasing the excess pressure in the pot.
