Review: Good replacement gaskets - There was an initial order mix-up, but the seller followed up immediately and corrected the issue promptly and courteously. Once I received the correct product, they worked perfectly for my application. I was replacing the old red rubber ring seals on some of my wide mouth flip-top canning jars, and wanted to use silicone instead, as it tends to hold up better and not deteriorate or crack as quickly. They fit and seal perfectly. Incidentally, they sent me the silicone disk lid inserts first by accident, and those work really well in the ball/mason plastic screw-on lids. easy, fast, truly water-tight, and (importantly!) not hard to unscrew after.

## Questions & Answers

**Q: What is the thickness of this gasket?**
A: This is a guesstimate as. I don't have access to them right now but I would say about 2 mm thick.  You will notice a slight difference when closing the lid when using these gaskets.  I'd say they are very useful and seal very well.  I know I will be buying more.

**Q: what are the actual dimentions of the outer and inner ring?**
A: The actual dimensions are:
Inside Diameter - 2.00"
Outside Diameter - 2.75"
Thickness - 0.0625" (1/16")

**Q: It says they are 'regular' at 2.75" diameter, but a regular Mason jar's mouth measures 2-5/8" How do they fit regular jars?**
A: They fit in the white twist-on lids.  When screwed down on top of the jar, the mouth of the jar hits the centerline of the ring perfectly.

**Q: I have wood lids for canisters that need new gaskets. The measurement is good but will they fit into the groove of the wooden lid?**
A: I use them on metal lids. The gasket is 3/8" wide & 1/16" thick. I hope this will help.

Does the job but could be just a little thicker so that it would stay in the cap when stored.

### ⭐⭐⭐⭐⭐ They surprised me!
*by K***R on May 31, 2021*

I had gotten some white Ball jar lids (the ones that aren't used for canning, just storing) and was disappointed that they were not even close to being leak-proof. I resigned myself to only using them for dried foods or those without liquids. Then I saw these gaskets and decided to give them a try. When I compared them to the inside of the lids, I was afraid that they were too wide -- they don't fit into the indentation around the circumference of the lids. But I decided to try one anyway. And it worked! No leaks at all. I put the whole thing (lid and gasket) in the dishwasher and both came out clean. They separated, but that's no big deal; I just put the gasket back into the lid for next time. Now I have a lot more usable lids. I recommend them!
