Size 3 Green Neoprene Rubber Stoppers are tapered Rubber Stoppers that will plug food containers, lab vials and other openings. Manufactured from Neoprene Rubber. Neoprene Rubber is suitable to a temperature of 275 degrees F and suitable for use with petroleum products, minerals, oils and fats.
Used to plug holes in plastic plates outside. The material seems to be high quality and flexible. Will have to wait to see if they hold up under outside weather conditions. Quick delivery.
