if you bought the 10 gallon plastic fermenter than I think you have to buy the lid to go with it. No reason to risk your brew over a cheap lid._x000D__x000D_Good for the price, fairly good seal but loose enough you don't need an airlock. Wouldn't leave a brew in the fermenter with this lid for more than a couple weeks.

perfect fit on 10 gal fermenter doesnt need an air lock cause not a air tight fit so after big fermentation make sure you transfer into a carboy to reduce risk of contamination
