Good evening I have not found any suitable rubber rings among the Weck articles. But under the article no. 55685639 Tala sealing ring set, 9cm diameter, 6 pieces I have found an article that might fit. I personally bought the tumblers to make desserts that I can tumble. I hope I have been able to help you. Kind regards A. Bolt
