Oooops - maybe the description differs from the box - I looked at the enlarged box image and it does NOT have the 7A.
This is the problem I had last year about this time when I needed parts for my old Best Maid canner. That was why I got the All American so I wouldn’t have that problem as they don’t use seals - it is metal to metal.
Good Luck...
Thanks, DW, your a gem! I appreciate the info and link you posted for the seals as I wouldn’t have had the time to search for it myself right now. My dad’s health took a nose dive this past weekend and we are expecting only a few more weeks for him. Trying to get the kids home this weekend. The canning jar couple live on the way to my mom’s house, so I will be stopping there (hopefully to purchase)before getting my mom and heading to the hospital.
