IMAGES SHOW WHICH BOTTLES THESE FIT
- O-ring seals are made of Food Grade Silicone
- These gaskets fit perfectly in Xtremeglas Hydrate Maxx (insulated sleeve), and Duo lids and previous version (2017 and earlier) Hydrate lids. If you have a Hydrate bottle (silicone sleeve) purchased after December 1, 2017 these o-rings WILL NOT fit.
