Are these lids airtight? When turned upside down or shaken, do contents leak from the jars?

they seem to be airtight, but for extra caution i place a square plastic wrap piece at the top and twist lid. i mostly use them for dry goods.

These are one piece canning lids, designed for waterbath or pressure canning. They take the place of two piece lids and rings. The lids have a rubber seal so they would be airtight and not leak if the jar is inverted.

I use these lids when I give a jar of goodies for gift giving. Reclosable without giving a two piece cap.

I put water in one of the containers and turned it upside down several times and it didn't leak, but no guarantees. Hope that helps.

THEY ARE NOT AIRTIGHT!!!! Good for crafts or buttons I guess? The plastic seal between the metal cap and the jar is not designed to be airtight seal.

They are reasonably air tight. I can tip them over and my yogurt doesn't leak, but you need to make sure they are on snug. I think they'd be good for your purpose. I don't keep my spices more than 6 months anyway. only buy small amounts for that reason. Hope this helps. they are good jars.

They are air tight. I use them to store yeast and have never had a problem.

I haven't had any trouble with them at all. However, I don't go around holding them upside down to check. The seal is very good and there is a removable gasket for ease of washing.

Yes, they lock in place and have had no problems with leaking. It really is a nice set of containers.

Yes, they are. However, I still sealed everything up with a mylar bag before putting on the lid. They are very high quality buckets/lids that seal up very tight and once sealed, have a one time use pull strip to open them again. The lids will go on again without the pull strip...but I wouldn't think it would be air tight without that strip.

Absolutely Not, these lid are no were near that tight. They are better than nothing. If I need to shake them or turn them upside down I use other lids from other bottles.

They screw off. Someone in the reviews said they leak. I have not had that problem.Some weeks later -- yes, I am finding they do leak a bit. I wrap the jars in a paper towel when I take them with me now.Another update: they don't leak if you make a thicker yogurt, using powdered milk along with the regular milk! If your yogurt is thinner and has that layer of whey on top, then they do leak.

They're more than not leakproof, they're actually a little loose. Not so loose that the lids don't stay on the bowls, but loose enough they're clearly not air- or watertight.

The lids are quite well fitting and tight. I'm not going to turn a bowl of soup upside down over my head to prove it but I can say for normal use they keep liquids from spilling ...hold on a minute.Okay, I turned the small bowl half full of water with the lid on upside down over my head and I'm still dry. So, yes the lids are quite nice and tight.

Airtight. Hmm... I guess that depends on what you mean by airtight. I haven't put anything fermented or effervescent into them, where I might have seen leakage under pressure, but I had a thin liquid (ethyl alcohol, the drinkable kind), and if I just gently shook or inverted the jar, it leaked. If you're just looking to prevent odd tastes from getting into something you have in the fridge, for example, they're probably fine. But they are definitely not for preserving or canning.

All of the lids I have fit very tightly. On the large round ones, I have to pry them off with a knife handle. They don't leak or spill at all.

I don't actually know for sure,but I do believe they are air tight and leakproof because the seal is very tight around the dish. Just make sure when you wash the seal,to let it air dry completely,or stretch the seal outward towards you to wipe clean&dry. I had an experience where I didn't wipe dry the seal and had to throw it out because it turned black. But I do think they are good and air tight and leak proof. Good luck,and I hope this has helped you.

Short answer is no, they are not leak proof. There is no "gasket" in the lid and so when laid on its side, liquid will slowly leak out. With the shaker in, it seemed leak proof, but who would store liquids in a bottle with a shaker top?

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.
