Universal Carboy Cap – Blow-Off, Racking & Transfer Cap (3, 5 & 6 Gallon)

Universal carboy cap used during fermentation, racking, or cleaning of glass and plastic carboys.

The flexible rubber cap stretches to fit 3, 5, and 6 gallon carboys, creating a secure seal without the need for a stopper.

The two ports allow multiple uses during brewing or winemaking:

• Attach an airlock during fermentation
• Connect tubing for racking or transfers
• Use with a blow-off tube during active fermentation

The soft rubber construction provides a tight seal while remaining easy to install and remove.
