We know some customers like to grow into their equipment. That is why we designed the FLEX to be upgraded. When you're ready to step into carbonating your beer in your FLEX, you can easily upgrade to the FLEX+ lid package. The main features are the FLEX+ lid and high pressure lid clamp which are rated up to 15psi. This essentially turns your base FLEX into a unitank that can both ferment and carbonate!
-FLEX+ High Pressure Band Clamp
-1.5" TC x 90° Barb
-4" cap, clamp and gasket will be reused from your base FLEX
