## Questions & Answers

**Q: my weck jar lid is glass 80 what size rubber band do i need?**
A: You would  need the 80mm rubber seal.  My glass lid says glass 100 and i got the 100 mm seal. That is the measurement  of the top of the jar 💁🏼

**Q: Will these fit Ball canning jars?**
A: No the Weck jars are all custom sizes and nothing similar in size to Ball wide mouth or regular jars.

**Q: Will this fit a tall spaghetti storage jar?**
A: You would have to measure the diameter of the jar and compare it to the size  of the ring that will fit  They come in several sizes.  Good luck.

**Q: Are the seals dishwasher safe?**
A: Top rack only. We run them through the dishwasher all the time. No heat dry though.

After 7 years some of my seals stretched out and were not doing the job. Good value for replacement. Hopefully these new seals will last as long.
