Jar shortage

Hi DeadlyFruit, I tried the one-piece plastic tops but couldn't get an air tight seal so I ditched them. I got suspicious when I used one of those lids for a batch of QWET tincture and got alcohol all over my hands when I was shaking it. No matter how hard I screwed it down it still leaked. Jus sayin.
 
Last year around this time I had to order complete lids, they didn't have rings and seals. I was gifted 18 free quart jars, not wide mouth but I used them.
 
Smoklahoma sorry, I misspoke, mine are actually amber rather than cobalt. I got them for the same reason - to keep out UV light. Agreed the grey one piece lids are so much easier than chasing the two piece ones that always seem to pull a runner in opposite directions whenever I take them off.

Ckbrew I haven’t seen any white ones so not sure if there is a difference but the grey ones are made by Ball and they are designed for the jar. Are the white ones made by Ball as well and just another colour or are they another company?

grouchyoldman did you use the grey ones made by Ball or another type? I haven’t tested the lids with a qwet type liquid but I’ve used them on regular mason jars for storing leftover soups and stuff in the fridge and haven’t noticed any leakage (sometimes the jars get stored on their side to fit on the shelves so there should have been leakage if it was going to). They are supposed to be dishwasher safe (and I’ve washed them all in the dishwasher without problem) but they say on the package that they shouldn’t be used for canning because they don’t have a coating of a sealing substance that the rubber gaskets on the metal disks have so I don’t think you get a true air tight seal in the way the metal lids have but my experience has been that the seal is pretty solid (you have to be careful though that the lid is on straight and threading properly). I didn’t realize it but you are technically only supposed to use the metal disks a single time because of the glue substance on the seal. The next time you make jam or whatever you are supposed to use a new disk. I’ll test a plastic lid to see if it can hold a positive seal on a jar full of alcohol laid on its side.
 
The ones that I had leak problems with are white and they came with the jars. I should also mention that the jars in my case were the little pint sized ones and I think the white plastic lids had been through the dishwasher at least once. Maybe the heat from that warped them?
 
Machine shop worker eh, I was the dude you hated to see coming through the door at quitting time, cause it meant someone was working all knight. I did ovarhead bridge cranes,

I ran a couple tests last night to see how leaky my lids were (the one piece grey plastic lids made by Ball). I was hoping they would be ok because they literally say leak proof on them but it was a mixed result. I first filled an off brand jar with water (it said atlas on it and I think it was one of those spaghetti sauce jars not a true mason). It was a regular mouth jar. Regardless how tight I screwed it water leaked. Then I tried a Ball mason jar. It was a wide moth, one of the half sized jars. I lightly hand tightened it and it leaked slightly. I tightened a bit tighter but not reefing it down and that stopped any water leakage. I shook it up a bunch and left it on its side all night with no drips.

My takeaway is for some reason the lids don’t work as well on off brand jars. The jar top seems the same but there must be a small difference in some - glass thickness or minute diameter difference or something. It may be that the white ones don’t work as well as the grey ones but the grey ones do work work on Ball jars.

I don’t think I can post a pic in a sub comment so I’ll attach a pic of the exact lid and jar in the main comment.
