If you have an old Thermos with either a missing or broken piece that you are looking to replace then hopefully this page can help. It can be difficult at times to know the correct piece you need to get your favorite Thermos back together again. Below we are compiling a list of Thermos items as well as the parts that go with them. We also have dimensions of different parts because many pieces are cross compatible. This page is a work in progress, if you need any additional help feel free to use our Contact Us page.
