I bought these because the other plastic lid option I tried, leaked. I am not pressure sealing anything. Recommendations on leak-proof plastic top?

I like Ball brand wide-mouth and regular size plastic caps for sealing mason jars. I use them to store leftovers in fridge as well as for freezing. They work well and i haven't noticed any leaking. Be sure to allow an inch headspace when freezing foods. They are NOT to be used for water bath or pressure canning.

They work well for me i have water bathed, pressure canned and put up jelo with them. the rubber rings just needs to be in place on the jar and the lid to get a good seal.

they were intendedfor canning, but they will work as a regular sealing lid. lid needs to be fairly snug, but do not over tightenas it tends to deform gasket. also if jar seal edge and gasket are completely dry this may cause leakage. the gasket needs to slide on seal edge of jar so seal pressure. the only problems i have found is over tightening and dry on dry. one other thing is if it is not a canning style jar it may not seal, no matter what you do.

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

the lids I have fit firmly in place and I'm not afraid that they would leak with fluids. I use one of mine for cucumbers with vinegar. have had it almost a year now with no problems. if they do leak you should be able to get them replaced, free of charge.

I never had an issue with them leaking and I used them everyday for six months. The only problem would be if they are overly full then frozen, the top won't stay on then. Just don't fill to the very top.

The lids are the same in term of leakage. I use saran wrap before I put the lids on. That works for me.

Well, neither really. You push them on and there is a rubber ring that creates a seal. Does that make sense? It does create a nice tight seal that won't leak. However, on top you will either have the straw opening or the sipper side open. The plastic piece slides back and forth to expose one or the other, you can't have both sides closed. So, it's not going to leak on you as you drink, but you won't be able to throw these in a bag and go.

I never used a lid on this. Would not know where to get one. Perhaps cover it up with plastic wrap and put a rubber band around it.

They have been known to leak. I have discovered that if I heat the lids before tightening, the plastic will become malleable and I can tighten them further. Then, when they cool, the plastic shrinks and the lid will be tighter and not leak.However, just for picking up and shaking a drink, I have not had a leak with something like that. When they leak usually it's a very small seep.

They Don't leak... But you need to make sure you "snap" the lid close. if you don't hear the "snap" its not closed. :-)

Your question got me thinking, so I did a quick test. I filled one up with a bit of water, put the lid in place and tried 1) holding it upside down and 2) jostling and shaking it. The results: I did not see or experience any leakage. Hope this info helps you out!

I read in at least one of the reviews that someone had contacted thermos and they offered replacement seals. I've thought of trying to get a spare set of them just in case the need ever arises. I'm going to google "thermos" and see if I can track them down :)

Mine leaks as well - check the lid and see if the silicon ring is missing or damaged. I believe that's the cause for my leak. Still checking to see if I can replace that part...

I have had the same issue with these and find that I can basically only put things that don't "spill" in there. You have to gently close them and the lids tend to stay on, but they are NOT leakproof. Any runny thing like salad dressing spills.

I just received a new one today from Amazon and the top does not seal at all. The lid fell off in the shipping box. Am returning it for replacement and hoping that the next one seals properly, otherwise I'll have to purchase it somewhere where I can test it before buying.

No, I have not experienced any leakage. There was one time I had some leakage, but it was because I didn't screw the top on correctly and got it cross threaded. As long as is the lid screwed on properly and snug, there has been no leakage.

The lids fit snug. The dividers are deep. As far as leak proof, I'm not sure what you plan on doing with them. If closed and left upright I don't see them leaking.

I also had a cracked plastic top but it occurred from me trying to jam it on over something...my fault. I tried to seal it up and then tried to tape it but with no luck. I threw that one away.

Sorry, not these, use the Tattler lids for canning. These have no seal on them.
