The diameter is such that it will fit perfectly in the Brewzilla 65L. We cannot recommend that you use it for any other purposes or that you make something yourself to work with the 65L Brewzilla. Brewing is slightly dangerous as you're dealing with hot liquids that can cause burns so we can only recommend that you use the product for the exact purpose to avoid injury.

This replacement part is just the tube/pipe itself and does not come with the false bottom. We apologize for the confusion.
