Tapered Rubber Stoppers for Brewing, Winemaking, Fermentation, Bottles, Carboys, Tubes & Containers
Rubber Stoppers are a practical sealing and connection solution for homebrewing, winemaking, beer making, cider, mead, fermentation, bottles, carboys, tubes, containers, and compatible vessels. Their tapered shape helps create a snug fit in compatible openings, making them useful for beverage-making setups, storage containers, sample vessels, and general plugging applications.
Available in both solid and with-hole styles, these rubber stoppers let you choose the right option for your setup. Use solid rubber stoppers when you need to close, plug, or seal an opening. Use rubber stoppers with hole when you need to connect a compatible airlock, tubing, or other accessory for fermentation, venting, gas release, or liquid transfer.
Available in multiple sizes from #02 to #13.
