Bottle Upgrades

I noticed some of the red seals on my flip top bottles seemed to be going hard. I bought 12 bottles back in 2023 and another 12 in 2026. Surprisingly it’s the latest batch that have the issue. I assumed that I could just replace the seals but they are glued onto the white plastic stoppers. I’ve purchased 12 complete flip top mechanisms and 50 silicone seals. They are much better than the original rubber seals and should never harden. Silicone is also much more heat and cleaning chemical resistant.
