Ball® Wide Mouth Mason Jar Plastic Storage Caps, 8 count is rated 4.7 out of 5 by 104.
Rated 1 out of 5 by from Please Fix the Leaking! As others have noted, these caps are not liquid tight. Why on earth would Ball make a plastic cap for mason jars, and post photos of them covering jars full of all manner of LIQUID CONTENTS, and then sell them to the masses when they obviously pose a leaky mess to every buyer? This is the 21st century. There are a bazillion plastic caps in the world that seal well enough so that a jar's contents don't leak. Surely if anyone is capable of making a leak-proof cap, it ought to be Ball, no? The ring seals I've seen on Amazon, etc. that can be added to these lids to make them leak-proof probably work, but yeesh, one of the great advantages to the plastic caps was that they are a single unit - not a 2-piece band and lid (which eventually rust or the coating deteriorates and they cannot be reused reliably). Now I have to buy another part for my plastic caps to make them work right? This puts me right back to the metal bands & lids, which have a number of disadvantages. Come on, why wouldn't Ball just shape up their plastic lid design and remedy this very obvious problem by improving the piece itself, rather than adding another part to it? I have to say, there is something pretty off-putting about having to buy an extra product to fix the manufacturer's lame design flaw in the first product that I already paid for (with the crazy notion that it would work properly). I was thrilled when I first bought these lids because I thought I was getting leak-proof portability and one-piece cap simplicity, but actually, I got neither. They're okay for dry ingredients, but that's about it. Sorry to rant, but this has been bugging me for a long time. In fact, I visited the Ball site for the sole purpose of finding out whether they had corrected their cap flaw, and was pretty disappointed to see they have not.

Rated 4 out of 5 by from Secret to plastic lids sealing I have used these lids for years. Yes, they leak if the jar and lids are different temperature since glass and plastic expand and contract at different rates. If you store liquids, then twist tight and refrigerate. When everything is cold, they will not leak if you are careful.

Rated 2 out of 5 by from OK for dry but doesn't seal for liquids The lids look nice but don't seal properly against the rim of the jar. The need to purchase additional silicone rings to ensure a seal makes the total package pretty pricey. Just had hot pepper sauce leak all over someone's hands this last weekend when the picked up the jar to look at the contents. Disappointing.

Rated 5 out of 5 by from Love these Lids I bought a box of these lids the first time I saw them. I use them for any jar I open and use them instead of the metal bands. No rust or corrosion ever. I am purchasing more, because I use jars for storing all kinds of things.

Rated 1 out of 5 by from They do not seal!!! Beware!!! These lids do not seal properly. When trying to shake the contents the sprays all over the place. I tried with multilple lids and the same happened with every lid.

Rated 2 out of 5 by from leaks easily I bought this last week. I was so happy because I make my own yogurt and keep them in Ball Jars. I purchased the wide mouth plastic tops because it is too expensive to use the metal lids for my purpose. I took them out of the box and put them on the jars in which I had placed water and they leaked. Not just a little, but a lot. I was hoping that this could be resolved by some sort of seal or a plastic lid with rubber, but I don't see this anywhere. I have had to use the flat portion of the metal lid to keep from leaking. I looked at the box and saw pictures of jars with liquid which is misleading since these leak. I even tightened them so tight they were difficult to get off. They could be useful if there was a seal of some sort. They could store dry goods.I will not be making this mistake again until Ball makes a seal to go with this.

Rated 4 out of 5 by from Wide Mouth Plastic Jar Storage Caps When giving away Canning goodies in a Wide Mouth Jar, I usually include one of these lids for them to use after they have opened the canning item they received as a gift. Several people have remarked how much they like it better than reusing the canning lids. 1) I gave it a 4 rating because they can leak a little if you use it with more liquid stuff in it for storage.

Rated 5 out of 5 by from Love these plastic caps. They won't rust! The fact that are plastic made is good as they will not rust. I use and re use them. Good sizes, I even use them with other jars besides Ball's
