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.
The FerMonster™ PET Fermenter is hard to carry, we strongly suggest that you purchase our carboy carrier (make sure it fits your specific size of carboy).
