Stretchable Sealing Caps
Silicone Rubber
Create an airtight seal around the tips of bottles and containers. These caps are flexible for a snug fit.
Compared to Buna-N caps, silicone caps fit vessels with larger diameters, such as flasks, beakers, and cylinders. They’re equipped with pull tabs—tug on the tabs to stretch these caps over the opening of your container. These caps withstand chemicals in high temperature applications up to 350° F, though they will swell if exposed to a solvent for too long. You can label and write on them with markers.
