MWI VETERINARY FOLDOVER LARGE STOPPER 1 COUNT

Wheaton Sleeve Style Rubber Foldover Large Stoppers are used on serum vials and other containers that don't need aluminum seals or overcaps. They can be used as an injection site for multiple dose entry. Made from natural red rubber, they have excellent resalable properties, making them ideal for multi-puncture applications. The hollow plug fits inside bottles, flasks, vials, or tubing to create a double seal.
