Wheaton 224100-020 Rubber 11mm Sleeve Style Stopper, Natural Red Rubber (Case of 1000)

Wheaton Sleeve Style Rubber Stoppers are plug stoppers with fold-over skirts. This type of stopper is used on serum vials and other crimp-finish containers that do not require aluminum seals or overcaps. Sleeve stoppers can be used as an injection site for multiple dose entry. These stoppers are manufactured from natural red rubber, a general-purpose rubber formulation that has excellent resalable properties, making it ideal for use in multi-puncture applications.
