Lab Stopper Material Spec Sheet
addition to our standard stocked items, we manufacture custom stoppers
in all durometers and compounds. Visit our Technical Data Section to learn more about different rubber compounds, durometer, and chemical resistance properties.
Tapered rubber stoppers are the most common configuration, but we can provide any shape plug, bung, or stopper you need for labware, bottles, boiler tubes, flasks, jars, test tubes or similar containers. Visit our Design Illustrations Guide, numbers 31-33 to specify your stopper needs.
