Overview

Our engineers designed a clear polycarbonate (same material as bullet proof glass) cap which allows you to see inside the top of the conical when it's fermenting. This has also been tested against common brewery chemicals and has held up against the likes of PBW and StarSan.

  • 4" TC
  • Clear polycarbonate material

Clever Idea

This is a very good idea, but the ****** condensation leaves the window too clouded to see through well.

Fermented in glass for over 20 years and being able to see the ferment in my Flex was the greatest!

Unneeded

It was not needed for what I am doing, but used it anyway. Quality as always is 100% & if you need to peek, you need this.
