Fido Gasket

I bought this for my Bormioli 3/4 L glass jar with a blue top. The gasket is a tight fit on the lid but after it’s in place the gasket provides a nice seal for the jar.

They fit perfectly and sealed tightly.

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

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.

Exactly the size needed for my jars

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.

I found some old glass jars with lids at my Mother's house. The old rubber gaskets needed to be replaced, but when I looked online there was some confusion as to what size to buy. I really wanted the rubber type of gasket as they are thicker than some of the new silicone canning rings out on the market. These gaskets or canning rings were perfect for my jars. I took some pictures with measurements to help others that are trying to figure out if these may fit their jars. These Bormioli Rocco replacement gaskets fit really well. I had to tug on the gasket just a bit to get it on the lid of the jar, but I didn't have to pull hard nor was it difficult to put on. I like that it stretched just a bit to form a tight seal around the glass lid. I am very very pleased with these and would buy them again. They formed a watertight seal when the lid is closed and clamped down. I hope the pictures help you decide if you can buy these too.

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.

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

They are a perfect fit for my glass storage jars, with the glass lid and wire closures. I'd buy them again! Excellent quality.

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

It was okay.
