To seal the 1 3/4 inch hole in the center of the lid with a #10 rubber stopper. Drill a 1/4 inch hole down through the center of the stopper. Then thread a 5/16 x 2 inch bolt with a fender, flat and lock washer into the narrow end of the stopper. Push the stopper into the center hole from the top of the lid. Add a fender, flat, lock washer and nut to the bolt end and firmly tighten them together. This will compress and expand the stopper in the hole creating an airtight seal.
|Modified 7 Gallon Fermenters In A G&E 7 Cubic Foot Chest Freezer|
The maximum pressure rating of the Chapman fermenters is 3 psi. Use care not to exceed 2-3 psi when leak testing or using the fermenter under pressure. Failure to do so can cause the fermenter lid to become disfigured. Other than that as per Steve Chapman "The fermenters hold up just fine for pressure transfers, and many other uses."
