5.0 / 5.01 ReviewEasy cap for beginner!Just started my first batch of dandelion wine a week ago. A few days in, I received a surprise gift of Midwest's beginner fruit wine making kit and add on. Yesterday, I transferred the must from the fermenting pail to the gallon jug, and was totally relieved by how easy it was to use this plastic screw on lid to attach the 3 piece airlock. As I have researched more equipment I learned about the rubber bung and am so happy I did not have to experiment with that for my wine making forays. The airlock is bubbling away merrily and I know that when it is time to transfer it again, no disasters will occur in removing this cap and lid. I am sure that me and the bung lid removal would not go well and may in fact cause me to reap destruction. Thanks Midwest, I will be making my own orders soon and will get some more of these nifty caps!May 12, 2014

It's better to put a 3-piece airlock in it, and attach a piece of 3/8" tubing to the center stem of the dis-assembled airlock to create a blow-off assembly, if desired. -Mike W, Midwest SuppliesWhat size tubing fits inside the hole on this cap? I need 3 more blow off tubes for 3 more 1 gallon bottles, thanks.BEST ANSWER: Hello,
You will want 5/16" tubing for a blow off tube.
