Blow-Off Tubes

A stainless steel blowoff tube offers several advantages over other airlocks and is used to allow fermentation gases to escape the fermenter while preventing unwanted organisms and oxygen to enter. Includes a rubber grommet and fits standard fermentation buckets. Grommet available separately.

Advantages:
- Does not need frequent refilling with water like small airlocks
- Rigid and stays in place. Does not float like plastic blowoff tubes
- Prevents airlock liquid from being drawn back into the fermenter
- Can be cleaned and sanitized more thoroughly than a plastic airlock and can last many years unlike fragile plastic airlocks
