Know before you buy
This over-pressure plug is designed for all Presto pressure cookers and canners manufactured after 1977. If your unit was made before this date, this specific part will not be compatible.
The plug acts as a secondary safety mechanism. If the primary vent pipe becomes blocked during operation, the plug automatically releases excess steam to prevent pressure from building to unsafe levels.
It is recommended to inspect the rubber plug regularly for signs of cracking, hardening, or damage. If the rubber shows any wear or no longer fits snugly, it should be replaced immediately to ensure the safety of your cooker.
Yes, the rubber construction is dishwasher safe. You can clean it in the dishwasher, though hand washing is also perfectly fine for routine maintenance.
No, this item is specifically the over-pressure plug only. It does not include the primary pressure regulator or the vent pipe assembly.
