Multi-Stoppers are manufactured of red silicone or green neoprene material. The rings are cut from the same stopper, each ring fitting perfectly inside the next. This allows for vacuum tight fit for all openings within stopper size range. The stoppers are ideally suited for glass working operations and chemistry labs.

Multi-stoppers made of red silicone are suitable for higher temperature applications with a serviceable temperature range from -100 F to +450 F. These stoppers are resistant to hot oils, fuels, oxidizing chemicals, sodium hydroxide and ozone.

Multi-stoppers made from green neoprene have better aging characteristics and are resistant to oils, solvents, ozone and hydrocarbons. The serviceable temperature range is from -40 C to +100 C.
