Rubber Carboy Cap
A flexible natural rubber cap that fits over the outside of a carboy neck rather than inside it, providing a secure and airtight seal. Each cap has a central hole for fitting an airlock. Available in three sizes to suit different carboy neck diameters, including glass carboys up to 54L and all straight-sided carboys.
Size Guide
- Small — external approx. 5.5 × 5.5 × 4cm. Not recommended for our carboys or demijohns as the fit is very tight.
- Medium — external approx. 6 × 6 × 4.5cm. Fits most of our carboy neck sizes and all straight-sided carboys. Fits slightly tighter on the neck than the large.
- Large / 54L — external approx. 7 × 7 × 5.5cm. Fits carboys with a wider neck such as 54L capacity carboys, and fits straight-sided carboys with a little more room.
