EcoPeaceful 316 Surgical Stainless Steel Mason Jar Lids WIDE Mouth -ORIGINAL DESIGN- Stackable w/Pull-Tab Silicone Seal. Rust-proof, Airtight, Leak-Proof, BPA-Free, PVC-Free, Vegan - Not for Canning

Beste Entscheidung! Können in die Spülmaschine, halten absolut dicht. Kann ich uneingeschränkt empfehlen. Viel besser als die Original-Deckel

Got this product in both the regular and wide mouth (since I use mason jars for storage and not canning). I love using these!! They've been durable, easy to use/clean, and sleek (all my can lids match and I don't have to think about finding the right one since they're all the same). There's been little signs of wear, and best of all, no rust! It's super convenient to clean: I can separate the gaskets easily to pop into the dishwasher. And the lids are stackable (unlike some of the other reusable stainless steel/silicone lids I've purchased elsewhere). They've fit any jar that's originally come with mason-jar sized lids and I've had no problem. They've also generally been leak proof (but some liquids will pool a bit in the lid/gasket, so sometimes there's some dripping from the lid after opening).

If these really are 316 SS, that would be impressive, if somewhat over the top. I can't test that claim without damaging one (color of incandescent sparks coming off a grinding wheel), and frankly I don't care enough to do that, because 304 SS is adequate to the task. They are definitely austenitic stainless. So let's talk form. To my surprise they're decently thick gauge and fairly rigid. I assumed the people claiming poor fit on canning jars had squeezed and deformed them, but no. Canning jars and lids have well-known standard dimensions. These fit perfectly. So now I have to suspect people are trying to put them on non-standard jars, maybe pasta sauce jars that look like canning jars, or jars with damaged threads. I don't know. The difficult removal problem is simply because these are one piece. For canning, a dome lid is pressed straight down onto the glass by a separate ring. That's absolutely necessary for canning; it avoids damaging the resilient seal while screwing it on and allows prying it straight off to use the contents. It also allows removing the band after cooling to use on another jar, and to keep it from rusting, though surprisingly few people do that. Unscrewing a vacuum-sealed lid is practically impossible (which is why pasta sauce jars with one-piece lids don't use standard threading). Well, this isn't a two-piece lid, and the gain in convenience comes at the cost of hermetic sealing. It's to be screwed down only until contact with the silicone ring. There's no advantage to tightening beyond that, and screwing it down farther means unscrewing involves pushing a long track of glass against squished silicone. People complaining that these don't seal like canning under vacuum are simply admitting that they bought the wrong kind of lid. Hermetic sealing of wide-mouth jars requires 2-piece single-use canning lids; otherwise use jars with much narrower mouths, with much less friction to overcome, and screw their lids down tight. Incidentally, the idea that the embossed branding compromises the seal is nonsense. The silicone ring fits snugly inside the lid, spanning the embossed area. Closed spaces inside the sealing ring are of zero consequence. None. And denigrating them because the silicone sealing ring absorbs pigment? I don't know what to say. The world must be a terribly disappointing place. The other style, with silicone covering the entire underside so food never touches steel, makes 316 SS even more overkill, and reduces the security of jar stacking. The ring seal of these sits in a well, which becomes a bulwark on the outside, not tall but enough to keep round jars (not squares) from sliding off. Incidentally, they do dome in the center, so if you close one on something hot, as it cools it will suck that dome down just like a canning lid. That will let you know if the seal is airtight. An airtight seal counts for little if the contents and jar weren't sterilized, but does tell you the jar wasn't sucking in airborne microbes as it cooled. Or, if it pops up, that it has done just that. I bought these for a friend, a canning jar fan, not expecting to think much of them. 316? Yeah, right. Fits like a canning band? Doubtful. Sturdy construction with a thick high-quality seal? Typical advertising exaggeration. But I have to say, they are excellent in all respects. I'm actually quite impressed; I can find no deficiency or flaw. The brushed stainless surface looks good new but I'm sure will show scratches if used as I expect these will be used, but the point is that I expect them to be used A LOT. Canning jars as long-term storage suffer a durability mismatch with normal lids. These turn canning jars into forever jars.

Good quality, both seal and lid. Different feel to screw on but anyway, forms a good seal and lid sits at proper depth. Well packed without any plastic. Happy with purchase

The stainless steel and silicone are both high quality and seem like they will last forever. I have both the wide mouth and regular mouth versions, have used them a lot, have run them through the dishwasher many times, and they are still like new. I like that the silicone gasket is easy to take out and put back. I put the gaskets in my dishwasher’s utensil caddy, and the steel lids on the top rack. It’s best to let them air dry more after they come out of the dishwasher, as water tends to remain in the threads of the lid. Also, a little-known fun fact: metal that doesn’t have any pointed bits is generally safe to use in the microwave. I’m not sure if the seller would bless this, but I have used these in the microwave repeatedly with zero issues. (Just make sure the lid is loose so pressure doesn’t build up.) The lid contains splatter and helps the food heat more effectively by retaining some steam. This is especially convenient when heating up frozen stuff. Ball jars + these lids have become my main system for meal prep and storing leftovers in the freezer. I especially do this with chili, cooked whole grains, and rice-based meals. I haven’t personally had any issues with fit or seal with my Ball jars, though I guess I also haven’t tested it rigorously, or ever needed to trust the seal with my life. I do think these can be a little more fiddly than plastic lids, or lids where the gasket is glued on. e.g. You need to make sure the gasket is the right way on, and properly seated all the way around, before you tighten the lid. And sometimes you need to take care to line up the threads so they catch properly. You also need to exert more strength to get a good seal than you would with a softer spongier gasket material, or with those two-piece canning lids that come with the Ball jars. But for me I got used to that, and I think it’s worth it for the healthier materials, longevity, and ease of cleaning.
