Product Identity
This pack contains three natural cork stoppers sized 1" x 1-5/16" x 1-3/4" for sealing thermos bottle openings. They suit home users, laboratory staff or anyone needing to replace worn or lost plugs on compatible vessels. The stoppers arrive new and ready for immediate use.
Bundled Value
A three-piece set provides spare stoppers so a clean replacement is always on hand when one is being washed or has been misplaced. Having multiples reduces downtime in a lab or kitchen because a fresh plug can be fitted without waiting for the original to dry. No additional software or hardware accompanies the corks.
Capacity and Limits
Each stopper fits the stated dimensions and creates a friction seal for temporary closure of suitable bottles. They are not designed for pressurised containers, long-term chemical storage or openings outside the specified size range. Buyers needing tapered profiles, larger diameters or permanent airtight seals should seek alternative sealing solutions.
Highlights

Questions about this item
How often should the 64464 cork stoppers be replaced with daily use?
Cork compresses over time; plan to swap the stoppers when they no longer seal the bottle neck tightly.
What fails first on the 64464 stoppers during continuous sealing duty?
The natural cork material dries and loses elasticity, which ends the reliable seal before any other part.
Do the 64464 cork stoppers develop odour or heat after sitting in a thermos all day?
Cork is inert and adds no heat; any smell comes from the bottle contents, not the stopper itself.
