These reusable rubber sleeves slip over perforated flasks to contain investment material during filling and help prevent spills while vacuuming. Moistening the sleeve before placing it over the flask makes fitting easier. Remove the sleeve prior to burnout. Dimensions listed indicate the flask size each sleeve is designed to fit.
