Question: i need a sealing ring for an old time   Model # 620-46000  what do i buy
Document: Sealing ring was exactly as described. Arrived in time for processing our garden produce. Thanks!
This sealing ring is just what we needed to use my dad's pressure canner. It was an old one and we couldn't find any seals locally.
I have an outdated pressure canner and needed a new sealing ring. Like others, I researched and found this product to fit my model. When changing the ring it seemed like it was a tad large; however, went ahead with the processing (I had a load to go) and it worked great. Upon examining the ring after the load, it was perfect. I had purchased this replacement before and had no problems.
This is just what it is described to be, a quality sealing ring (gasket) for the Presto pressure canner. This seems to be a more supple and resilient gasket than the one that came with my canner. Works well.
Our old Presto pressure canner model 01780 had started to drip water around the lid. This new seal fixed it right up.
It's great to be able to buy parts for things in these days of disposable everything. Mom gave me here old pressure canner, and I replaced the seal and plug and it works like new! Then, my sister hooked my up with a bunch of fresh green beans, took the canner to mom's, she taught me the ins and outs of canning, so now I'm hooked!
It's been a while since I've done any canning. I've used this seal about 3 times now and it works ok, but I miss the old style that wasn't so flared-out. The seal also seems to be stiffer after just a few uses than the ones which were manufactured in the USA. Make sure you give it a thin coat of vegetable oil before using. Time will tell.
I have put off getting a new gasket for some time. I received it promptly and I should have done it years ago. I now have a snug fit and don't have to work to get the old seal to fit in the cover. It came with two types of safety plugs so you could use which ever fit your canner. It even had instructions on how to put it in though it is very simple.
The ring fit perfectly, and the kit includes two different safety plugs to cover whatever model you happen to have.The pressure canner doesn't leak steam around the lid at this point, and I'm very happy.
I received shipment in two days, from Amazon Prime, outstanding service. I replaced both the sealing ring and safety plug on a used canner I bought at the swap meet, for cheap. This restored the canner to perfect working order and I have a nice canner for a total investment of $20.15. Recycle, recycle, recycle.Presto 09905 Pressure Canner Sealing Ring/Safety Plug Pack
