These 38x200mm (1.5x8") giant glass test tubes, have a nominal outside diameter of 38mm. If you have a hole that is slightly wider than the OD of the tube, an o-ring or elastic band, etc. placed under the rim may fix the problem. Rubber o-rings are generally available in hardware or plumbing supply stores. We do not sell O-rings.

Here are some ideas our customers have told us about how they use these really big test tubes: Test Tube Concrete Vase; Coppercroft Test Tube Vase; Wall Mounted Plant Propagation Station.

I purchased 38x200mm test tubes to replace rain gauge tube that broke & I could not locate any other option local/online that would fit the - apparently - special size for the rain gauge. While I was disappointed the test tubes did not have incremental markings (for rain measurement), since the test tube fit the rain gauge perfectly, I was able to transfer markings from prior/broken tube to the new test tube. Subsequently, able to use the new test tube for my rain gauge.
