Are the rubber gaskets reusable?

Yes! While we can’t attest to their actual longevity, due to the varying conditions of use, we can say you should expect at least 6-8 uses per gasket before considering replacement. Much depends on the type of canning being done, and the length of time in storage on sealed jars. A gasket used in for pressure canning, and stored for long periods of time will not last as long as one used in a water bath and opened within a few months of processing. Stronger vacuum created in pressure canned jars, and long periods of storage will compress the gaskets more, keep them compressed longer, and therefore make them want to retain that compressed state faster. That being said, a pressure canned gasket, stored for 1-2 years, will still provide at least 6 uses before stretching to the point of needing replacement.

Additionally, the gaskets are also made from a food grade material, in this case, food grade nitrile rubber. They contain no silicone and therefore not prone to silicone related allergies.
