Replacement Rubber Gaskets for Fido Jars, 3.5" Size, Pack of 6

Fits perfect and works like a charm!

I needed one of these for an older clamp-style Fido glass cannister where the rubber gasket had yellowed. I measured the gasket I had and it seemed to match the measurements given on the write-up. But the cannister I had was about 15 years old so I was unsure when I received these and it looked a bit too small. But with a bit of push, it fits perfectly and will seal beautifully. Makes sense it should be snug. Not sure what I'll do with the rest of the same size gaskets in the pack but I guess I'm set for life on this cannister. So, you know, one less thing.

Will second whomever reviewed that these are the ones you are looking for for use on that old Italian jar you just thrifted. Old ring was cracking measured 3.75" around, but this product replaced it flawlessly. Also this looks, feels, and behaves like thick-ish rubber, not silicone, if that's what you're looking for. Great seal. Fits several large sizes.

I have quite a few glass storage jars whose mouths are slightly larger than the newer crop, and have had difficulty finding replacement gaskets, a task made more difficult by inconsistent labeling information by vendors at Amazon. After extensive research, I bought these gaskets thinking they would fit my jars whose original (aged) gaskets have the following dimensions: gasket outside diameter - 4" (100 mm) gasket inside diameter - 2-7/8" (73 mm) jar width to center of opening - 3-1/2" (85mm) When I received them, I discovered the dimensions for these gaskets are: outside diameter - 3 1/2" (90 mm) inside diameter - 2 7/16" (62 mm) I almost sent them back. The only reason I didn't was that I was unable to find the "right" size anywhere. I tried one on a jar, and was pleasantly surprised. These Bormioli seals are made from high quality slightly elastic rubber that easily stretched to the larger opening. They are dense, but not as hard and inflexible as the orange seals or lower quality white seals. They are also the proper thickness, unlike some of the other thinner seals sold here. It took a bit of maneuvering to get them on (three hands would help), but its not stressing the product, and once installed they are held securely on the jar but still allow for some adjustment. Do NOT buy the 4 1/4" seals (outside dimension)thinking it's your next best option. They will fall off every time you open the jar and drive you crazy. You want a bit of stretch to hold the seals onto the lid, and I suspect the quality of this product means they will survive the elements a bit longer than the original set. I tested for water tightness and the clean white color is a big plus for me. I hope this helps others avoid the same frustrations I went through. BTW, the important dimension that everyone seems to forget is the glass ring in the lid, which is what the gasket will fit to. That dimension is 3" on my jars. You want the inside dimension of the gasket to be smaller than that size so the rubber stretches enough to hold the gaskets in place. Unfortunately, manufacturers don't include that dimension anywhere in their product information. •••••••••••••••••••••••••••••••••••• May, 2017 - 5 years later, none of these gaskets have deteriorated or hardened. They are all still just like new, with no stains or cracking. They are much better quality that the old red gaskets they replaced.

Work as promised. Have several jars that require these. Never disappointed.

For the record, the unstretched gasket has an outside measurement of about 9cm or 3.5in and an inside diameter of about 6.5cm or 2.75in I bought some old ceramic locking canisters at goodwill and some of then needed new gaskets. I replaced all of them for consistency (and so it was easier to clean the canisters, some of the old gaskets were pretty grody and decayed). I have three canisters and there's six in the pack, so I still have three gaskets left as backups. They're not a perfect fit, and I'm not sure how well they really seal but the seals are visible and appear to be squished between the lid and body of the cannister as they should be, plus it seems to keep the rice and pasta fresh enough. Here are the measurements, they're not super exact, but hopefully it will help you decide if this is the right size for you. I measured the inner bit on the lid that the gasket had to fit around, which is the same as the stretched inner dimensions of the gasket, and then the stretched outer dimension of the gasket, and finally the opening of the cannister they needed to seal. The inside diameter of the lip on the lid that the gasket had to fit around was about 8.5cm or 3.375in. You have to fight to get it on a little, but I think that's supposed to be the case. The outer diameter of the stretched gasket was about 10.5cm or 4in. The opening of the jar was about 11cm or 4.5in. As you can see the gasket doesn't quite match the opening of the cannister, but the inside of the cannister slopes a little inward, which pushes the gasket up and as I mentioned, visibly squishes it against the edge when closed.

These are very nice but they are specifically for a certain brand of jar as indicated in ad, jars for canning. I keep trying to find a quality replacement for my other jars. These are unfortunately too small by just enough that they fell into every single jar I tried them on. This seems to be a problem for others - finding a good fit at a decent price. I won't return mine because the reason for return is not a seller or shipper fault and I don't want to pay return shipping - I will sell them at my next annual garage sale. So, I took the time to measure my jars and these gaskets and to take a photo of the jars so buyers can hopefully figure out if these will work for them. All my jars were thrift purchases at $1 each so all very mismatched but need the same size gasket. I used a Stanley metal straight-edged ruler for accuracy: each inch is 16/16th's, and all measures are across (diameter). These Gaskets: inside = 2 & 10/16ths outside = 3 & 8/16ths (3 1/2") Gasket (red/photo)inside = 2 & 14/16ths outside = 3 & 12/16ths (3 & 3/4")) Jars (in photo): 1- inside = 3 & 7/16ths outside = 3 & 11/16ths (top, arc France, bottom Made in France, 3L) 2- inside = 3 & 6/16ths outside = 3 & 11/16ths (top made in Italy no size, all Italian words) 3- inside = 3 & 8/16ths outside = 3 & 11/16ths (top KIG Indonesia) 4- inside = 3 & 6/16ths outside = 3 & 11/16ths (top HERMETIC, bottom 500ml made in England) The red gasket, although a bit large on the outside, does work for all 4 jars in photo.

Did the job!

Le quedan exactos, son ideales para los frascos de la línea Fido. los frascos con lavarlos y cambiarles el anillo ya parecen nuevos. Los anteriores ya estaban bastante cuarteados y gastados ya llevo varios meses con ellos y siguen como nuevos.

Sehr gute Dichtungen, gutes Material

O anel é de boa qualidade e atendeu perfeitamente nossa necessidade.

It was okay.

Good quality
