Wheaton Sleeve Rubber Stoppers

Natural Red Rubber Sleeve Stoppers. Sleeve stoppers are plug stoppers with fold-over skirts. This type of stopper is used on serum vials, serum bottles and other crimp-finish containers that do not require aluminum seal or overcap. Sleeve stoppers can be used as injection sites for multiple dose entry. Rubber sleeve stoppers are manufactured from natural red rubber, a general-purpose rubber formulation that has excellent resealable properties, making them ideal for use in multi-puncture applications.
