Univen Pressure Cooker Gasket Seal Compatible with Mirro S9891 S-9891 M-0396 M-0398

Great product fits great

After 30 years the gasket on our old Mirro-matic pressure cooker Mod 0398 gave out. I matched to model number on A.com, and ordered. IT WORKS PERFECTLY!!!!

Do not buy from this vendor. The gasket did not fit. It was at least one half inch too long and not thick enough to fill the gap between the lid and pot. This gasket blew on the first use. I was fortunate not to get hurt but please heed my warning.

If you own a vintage Mirro or Mirro Matic (Models M-0396 or M-0398), this Univen S-9891 gasket is a non-negotiable safety component. However, be very careful where you buy it—I found it for $19.29, which is twice the price of other reputable parts sites. Why Precision Matters: Safety First: This is not a universal gasket. It is specifically engineered for the M-0396 and M-0398 series (including suffixes like -11 and -35). Using a "close enough" fit on a pressure cooker is dangerous and can lead to seal failure under high pressure The Fit: Univen is a trusted brand for these older models, and when you have the right match, it provides a perfect, airtight seal that brings an old cooker back to life Maintenance Tip: Always check the model number on the bottom of your pot before ordering to ensure this is the exact match for your unit The Value: While $19.29 is expensive for a single rubber ring, it is still cheaper than replacing a high-quality vintage pressure cooker. That said, if you have the time to wait for shipping, you can save 50% by ordering from a dedicated appliance parts store instead of a general marketplace. Bottom Line: An absolute must-have for the specific Mirro models listed, but the current price is a bit of a sting. Check your model numbers twice and your prices once!

It is of good quality and the right size

It seemed a little loose at first but it did work ok

We've been looking for this size gasket for almost a year. Fir perfectly, works perfectly. Not much else you can say about a gasket.

looks like it should but it is actually slightly too big a diameter,does not seal properly due to oversize,pressure cooker boiled over in multiple spots,re installed old one which is a little brittle but at least it seals properly.And yes I pre-treated with oil as suggested
