Twin Bubble Lock

(1 review) Write a Review

Twin "S" Airlocks are great for secondary fermenters.  These work better for secondary vs primary because they show the pressure coming out and are more sensitive.  Sometimes primary fermentation is too much for them and they are more difficult to clean.  ***Stopper that airlock is setting in photo is not included.
