How tight are the rubber seals? Do they come off after opening the jar? Do you have to constantly adjust them each time you open and close?

They don't come off after opening the jar, but I do make sure to readjust them while closing the jar just to make sure that the seal is tight.

Matthew,So far the seals haven't let moisture in and kept my spices fresh.I guess the answer would be no the seals haven't come off when I opened my jars and seals are tight enough to keep spices moisture free. The only problem I had was that one of the jars was crushed/broken when I recieved them. Otherwise they're very nice and do the job. ♥

They screw on and have a rubber gasket to seal them. But sometimes they get loose

yes, I used one of those rubber jar openers to get a good grip then pull it straight off. Annoying but once you get by that, it works great!

This is what is annoying about this product on this site - the most important issue being inside diameter is never mentioned; but judging from previous questions and answers, I'd say you need the ring labled: Kilner Replacement Rubber Seals for 12, 17, 34, 51, and 68-Fl Oz Jars, Pack of 6, or the middle size, meaning it should stretch to fit 3 inch diameter. Even the Kilner website doesn't give dimensions which are helpful.

These are made of "silicone rubber" which is a synthetic rubber that is much more durable than ordinary rubber. The rings are high quality but much thinner than the original ones on my jars. You may need to put on two to make the same thickness, or adjust (bend) the metal bands to tighten properly with the thinner rings.

I did adjust the closure and made sure the seal was okay. That seems to have taken care of the problem the last couple of times I used it.

Yes . Unscrew the screw on lid and then use your jar pop to lift off the sealing lid. Works great!

The rubber seal can be removed. I use the tip of a paring knife and carefully lift the seal and then pull it out by hand. Wash the rubber seal, wash the lid, when dry replace the seal. It works.

no, it should be tightly sealed. On my original jar that is 10 yeas old, the rubber piece is cracking but neither it nor the blade is loose!

Thank you everyone for your replies. I 'was' concerned about over tightening, as they do appear rather thin; but it's good to know they have been re-used repeatedly. If my first choice for sealing my fermented veggies fails, this will be my second choice. Thanks again for all the help and personal advice! : )

Thats a good question. basically, the curved part of the jar opened just lifts the edge and allows air under the lid to make it come off easily. The flat part should be fine. It takes very little effort to put air under the screw band..the flat part doesnt seem affected. Just don't be too aggressive, you[ll see what I mean

I was able to remove the seal fairly easily. You will need to use your fingernail or something like a butter knife to press the seal towards the inside of the lid in one of the corners and then kind of roll it. You will be able to pull the seal out easily once you get it loose in one spot.

I've cut them out of wax paper a few times at the beginning, but in the end I just don't bother -- the sprayer seems to work just fine without the gasket. I've not had any problems with the jar sealing even with no gasket; There is a vent in the top in any case. Give it a try, I think you'll find the same.

I have never had a problem with the seal. Although you don't have that little bump you have in other jars, this one is just a matter of trust. I tighten the lid really good. When I make jam and after I put the lid on, I just tighten the lid, turn the jar upside down (Inversion) and set for 5 minutes. Turn over and it is sealed. Now remember the jam is hot and would seal as would a ball lid on a jelly jar. Are you putting in a cold liquid or hot liquid? Cold may make a difference.

I called the company that makes these and I followed their recommendations, which was scarey since they said don't tighten the lids til they are done processing....but it worked great. The tattler ones won't seal if you screw them tight like the metal lids before processing. I used to use water bath method for everything, so I get it. These will seal if you just finger tighten to start with and tighten when you bring them out of the canner. I did some meat and ham balls in them plus other things and they stay sealed.....after 24 hours, remove metal rings

Yes it seals mason jars, but you have to buy the attachments for the jars. Basically you put the plastic attachment on the top of the jar with the rubber ringed top, push the button, and when it's done you just remove the plastic top and the top is down tight. I use it all the time. This is a good example: FoodSaver T03-0006-02P Regular-Mouth Jar Sealer

I have never really had any issues. The jar has never had a shrink wrap seal on it no matter where I buy it. I just make sure that the jar is full and not leaking when I receive it.
