Fit good

The Weck seals do fit La Parfait. They are meant for wreck (made by weck brand) so Iwasn’t sure but order them anyway because they were cheaper. I don’t mind that they are thinner than the La Parfait brand or similar brands. It definitely works just fine for dry goods. If you’re canning and planning to properly seal the jar so they’re shelf stable, I personally would not buy Weck for LP.

Good quality and fit perfectly on Weck jars

These rubber seals are good, but they’re slightly off in size for the jar I have. I should disclaimer I don’t have a Weck jar. I have an unbranded jar that I brought from Big Lots that needed a new gasket. The average silicone gaskets are too small. These Weck seals were the closest size I could find. Unfortunately, they’re not thick enough so I had to put two seals on the jar. But I think it will do the job.

Did you buy one of those dandy Chinese ultrasonic vinyl record cleaner setups only to find that the label cover discs are a little too small? These, with the tabs cut off, provide that extra couple millimeters of label coverage, keeping them dry. Yes, they make the stack a little thicker, but just turning the thumb screw around backwards and leaving off the spacer made for a a perfect fit with the gaskets.

Used with Weck jars

The rings didn't fit.

I needed to replace the rubber seals on my glass jars and these worked perfectly.
