Question: Is this the proper gasket for a mirro M-0512 pressure canner??
Document: Ring fit well and was as described for the M-0512 pressure cooker. At first it didn't seem like it would but I haven't had any leaks.Really Amazon? 20 words. *sighs* It's a good gasket.
Important Information* If your model number is M-0512, M-0512-11, M-0522, M-0522-11 and if your model was made before Jan. 1983 then you need the 3440 Gasket.Thankfully, Amazon accepted return.
My Mirro pressure canner is from the 70's, 22 quarts. This gasket fit perfectly and I have used it several times. Worked so good I bought a second one to have on hand. I went to my local hardware store and they ordered 2, which neither fit. Amazon came through!! !
Yes folks, this gasket does fit a Mirro model #0406 16 quart canner/cooker. The gasket fit the lid of my pressure cooker almost perfectly. I say almost because when I first placed it inside the lid there was what seemed to be a definite excess of gasket material that I thought would likely cause problems.
I purchased this pressure canner gasket to replace one in a Mirro pressure canner that I have had for 25+ years. It fits well and I have used it multiple times this summer and it is doing very well. The only reason I gave it 4 stars and not 5 is that I'm not sure it will last 25+ years like the original one did but time will tell.
my 22 qt. M-series pressure cooker is old and I was unable to find a gasket for it locally. I was afraid it was not made any more but much to my relief it still is!! Working well. Thanks T-Fal/Wearever.
This gasket fits an old Mirro canner that I've used for over 30 years. Nice to know I don't have to run all over the country trying to find a gasket.
product description obviously does not match the product. This is a gasket for a pressure cooker, not a pan. Will it fit a vintage Mirro pressure cooker model M0512?
I ordered this gasket for an older model pressure cooker. The product number I gave was correct but once received it was not for my model. As a result it is not a proper fit and I cannot get up to pressure.Frustrating!
Purchased this gasket through Amazon in 2011. I have used the pressure canner several times since then. When I used it this past weekend, the canner started to develop pressure and then the gasket appeared to have blown out. Steam was escaping from the entire perimeter of the lid. I had saved the old one, so I tried again using it instead.
Answer: I bought this last summer and used it in my 12 quart Mirro M-0512 and haven't experienced any problems.
