How well do the lids seal? If the 2.5 gallon containers are on their side are they likely to leak? My application requires them to be on their sides,

They are built quite well actually. We used them in the Marines and you could place them anyway you wanted as long as the lid is secure. As far as for how long? No clue. Pretty durable as well. ..

I have had two for a couple years now and have never had a problem with them leaking. I am super hard on them as well

I can't speak to the 2.5 gallon containers but the 5 gallon should hold up. The bottom has the most reinforcement but the sides are very durable as well. You can purchase these from the manufacturer direct for much cheaper than most sellers on Amazon.

I have five of these containers and have found that a couple will leak when on their side. It doesn't matter how much I tighten the lid, they will leak. It's not a serious problem for me as I can leave them upright.

We have the 5 gal. models and although we have not carried them on their sides, I doubt they would leak. These are very well made, heavy duty containers

It might be alright. I know that I have to hold the container securely when pulling off the lid because it will create a suction when it comes off, hope that made sense. They do fit pretty securely though.

They seem to be pretty air and water tight ... Like with any container, there may be a little leakage, but my lid goes on tight and doesn't move when on. I had to cut holes in my lid for my bread gasses to escape.

I haven't tried to use them in this manner but, to be honest, I think that would be asking for trouble. These lids are tight, but not bulletproof. You should probably try to find something where the lid screws on tightly, rather than pushes down to form a seal. My opinion only.

The lids work very well! As for size, if you bought the jars new the words 'regular' or 'wide mouth' would be on the packaging. You may want to remeasure as a 2" opening is not a size with which I am familiar.

Yes, these containers do leak, they are not air tight. Great for non-liquid items however.

They work well on my half-gallon and quart wide mouth cannister jars, which have the metal clasps that clip down to tighten the glass lid up against the rubber gasket. This type jar used to be called an "easy seal jar." Hope this helps.

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.

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.

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.

The lids push on and seal quite tightly. They're very handy to use just be sure you put them in the upper rack of the dishwasher

They held in liquids very well in my freezer. I laid then on their side and nothing leaked. Hope this helps!

I haven't had problems with leaks yet. My kids love these...don't fill them up all the way otherwise when u close them it will spill over.

I got what is in pic. They sealed great for awhile, even with beer inside. But recently both lids started leaking a tiny bit.

No. They will leak if laid on the side. These jugs are not completely airtight.

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.

I use these mostly for my husbands lunches for things like pork and beans, pudding, olives, etc. However I just went and took one, filled it with water and put it on it's side and nothing came out so I shook it a bit and still nothing. When I press on the sides of the container the top bows up so even the air is staying in. I think they are mostly air tight and so far, I've never had one leak in my husbands lunch before. One caveat, these are plastic so if a lid or container is ever so slightly warped, it could possibly leak I suppose. Hope that helps you. I love these for lunches and portion control and I've bought them more than once.
