09985 Pressure Canner Sealing Ring for Presto 16 18 23 Quart

Fits and seals just like the original. It’s best to let it “relax” for a few hours before applying it to the lid.

I have a prestro pressure canner for years and actually never had to change the seal until recently when I noticed the seal's looseness and steam venting out of sides of the pressure lid . I thought I would have to go to the company to get a replacement seal due to the age of the canner ,but I thought I would check Amazon first and they have it so I ordered one but was hoping it was right. Well I got it and switched the seals and plug and wow they both fit perfectly and the lid is hard to tighten into place like it was new ,I reordered another one since we have hard water and that causes the rubber seals to weaken was faster than normally. Besides I'm pressure canning more these days so I want to make sure my equipment is ready

I started having failures in canning and doublechecked I was doing everything right! I started noticing water dripping out of the top, then I saw that the seal ring was my problem. It wasn't cracked, it was just loose. When I got my seal rings from Amazon I was eager to can something. I noticed how much tightly they fit! It is fixed (until next time, provided I remember)! I am getting old!!

Always keep extras on hand. Compatible with Presto 16 qt pressure canner. Time saving to have extra on hand just in case.

Well, I purchased this set as I wanted backups for our 2 Presto pressure canners. I noticed right away that they were a little (maybe .35-.5") to small. I returned them...well, I returned the original one in the set of 2. I decided to try it. The first time using it, a little water dripped for about 7 minutes, from the seal. Then stopped and the remainder of the canning time went well. All sealed. I have used it several times and now, no water dripping, seals, pressure good and jars sealed. I guess the slight difference did not hurt. I thought it would but was pleased to find out, it works.

The fit was perfect

Warning first time i went to use it. I couldn’t get the lid to seal on my pressure canner. It needed to warm up then I had no problem with closing the lid. Had a hard time finding a solution to my problem.

Ordered these about a year or so ago. Just went to replace one and these are too small. It has the correct part number on the label but it does not fit the 23 quart canner.

I have presto pressure canner 0178107. The first time I used the pressure ring it worked fine. When I tried to put the lid on the canner for a second batch the pressure ring fell right off the lid. I measured it against an unused pressure ring and found it had shrunk a good half inch and no longer fit.

I initially leaned towards giving this product only 2 stars. I have been frequently using my 23 qt and 16 qt Presto canners for the last five years and have already replaced both rings in the past. With this brand I struggled to lock and unlock the lids on the first attempt. No amount of pressure applied on the top of the lid helped. I eventually greased the rings with a little bit of olive oil and managed to lock them in. I left the lids in locked position overnight, hoping that the resistance will ease in the morning. Next day I had difficulty unlocking the lids. I have strong grip, so I eventually succeeded. But the handle screws on both canners had to be tightened. After using the pots, one of the lids is easier to screw and unscrew. Second lid is still representing a bit of challenge. I measured the diameters and weight of new rings. The measurements match old rings. It seems to me that something in the manufacturing process is not quite right.

Did not arrive with all contents I paid for.
