You will love the versatility of this stopper!
The Universal Stopper with Hole fits a 2.8, 3, 5, 6, or 6.5 gallon glass carboy. Also fits our 500ml Erlenmeyer flask, and can be flipped over and used in most bottles! Made with a longer taper from a different material from standard stoppers to minimize popping out when wet.
Please Note: This stopper will not fit in plastic carboys, Better Bottles or Speidel Plastic Fermenters.
