#000 Solid Rubber Stopper for Drilled Stoppers

#000 Solid Rubber Stopper for Plugging Drilled Stoppers

This #000 solid rubber stopper is a simple but useful little part for brewers who want to temporarily plug the drilled hole in a larger stopper. It effectively turns a drilled stopper into a solid stopper, which is especially handy when you need to move, shake, or reposition a fermenter without using an airlock assembly.

Instead of swapping out your stopper entirely, this small solid plug gives you a quick way to close the opening in an existing drilled stopper. That makes it useful during transport, mixing, degassing, or any situation where a protruding airlock would get in the way.

Why This Stopper Is Useful

• Plugs the drilled hole in larger stoppers so you can temporarily convert them to a solid setup
• Useful when moving a fermenter and you do not want liquid sloshing into the airlock
• Helpful for shaking or mixing during fermentation prep or ingredient incorporation
• Compact and inexpensive spare part to keep on hand in the brewery

Typical Brewing Uses

• Moving a fermenter from one location to another
• Shaking or agitating wort or must without an airlock installed
• Temporarily sealing a drilled stopper during cleaning, storage, or transport
• Keeping extra stopper plugs on hand for small brewery or winemaking tasks
