Frequently Asked Questions
How do I know if this plug fits my Mirro cooker or canner?
This plug fits Mirro and Mirro Matic models that use a rubber overpressure plug. It does NOT fit models that use a screw-in Safety Fuse or models with numbers beginning in 92***. Check your existing plug — if it's a rubber push-in style (red or black), this is the correct part.
Is this a genuine OEM part?
Yes — this is an authentic OEM part. In 2007, SEB Corp officially authorized sourcing of Mirro pressure cooker components directly from the original manufacturer.
What does an overpressure plug do?
The overpressure plug is a critical safety feature that releases excess steam and pressure if the canner or cooker exceeds safe operating limits, preventing dangerous over-pressurization.
What colors does this plug come in?
The plug may be red or black — this varies by model. Both colors reference the same part number S-9732.
What if I'm not sure this is the right part for my model?
