How to install the O-ring on the FerMonster™ PET Fermenter.

FerMonster™ PET Fermenter

With a wider 4” mouth, there is easier access for cleaning. It is made of heavy P.E.T. plastic.
  • Our Carboys do not use any plasticizer and are made with 100% Virgin material. Made with Food grade materials and BPA free.
  • Comes with an O-ring and air-tight ONE PIECE lid with a hole that will take our #10 stopper. The lid hole is 4.3 cms (1.7”) in diameter.
  • There are no ribs, only smooth sides, so no yeast or sediment will adhere to walls during fermentation.
  • Solid lid is available as an option (not included in the product sold as a separate item) so you can customize your lid (drill as many holes as you wish).
  • Completely taste and odour-free. It is also stain resistant.
  • Impermeable to oxygen.
  • 100% made in Canada.
  • Comes with 5-Gallon, 6-Gallon and 7-Gallon easy-to-read markings on the side.
  • Also they are big enough so you can use them as your Primary Fermenter.
