Blow-Off Tubing, 4 ft Long, 1.25" OD

This blow-off tubing is food grade vinyl, 1.25" OD and 4 ft long. Just jam one end of this tubing down the neck of a carboy and place the other end in a bucket half-filled with water or sanitizer and you'll never have another fermentation mess again.

Also, try a stainless steel blow-off tube or a great alternative to using a blow-off tube is to limit how much the beer foams up by using Foam Control.
