FastRack Drilled Rubber Stopper (#10-3 Pieces) | Solid Rubber Stopper Bungs for use with Fermentation Airlock | Durable Carboy Bung |Tapered Bung for Corking Home Brewing Glass Carboys

Excellent fit for my five gallon water jugs

Just the rite fit

The quality is great but the size of the hole where the bubbler goes is way too small. I am just going to drill it out to make it bigger.

Nice quality rubber plug with the correct size whole to add your own airlock. Perfect for the larger carboys.

Fast shipping

Fits my 6 gallon plastic carboy

I was worried by the amount of reviews saying it was not drilled or drilled incorrectly and product was not rubber but I received exactly what I thought I was getting.

Fits perfect on the bottles we bought from Amazon

Size is right. Work as intended.

Only one needed, but cost wasn’t too extreme and maybe in a few years I’ll require another one if I ca find out where I put them by then. Lol. It would be nice if the stopper was ready cut, as rather tricky cutting into this dense rubber. All in all things went well and the birds are happy to have a secondary place to drink and bathe.
