Nope. No gaskets. We went online and found a source for 4-5 gallon food-grade plastic bags and used them for liners (with twist ties) in these buckets. We have not added the oxy-packs since we do not expect the buckets to be perfectly air tight, even with the plastic bag liners. But at least we've got bug and moisture protection at a price we could afford. BTW, you can get at least 15 rolls of toilet paper in one of these buckets. That makes pretty cheap water-resistant paper storage.
