Description

This stopper has two holes and we use it in the production of our stopper thermowell. It features one 3/8" hole and one 1/4" hole. A racking tube or stainless tube can be inserted into the 1/4" hole with the aid of some lubrifilm, forming an airtight seal, and the 3/8" hole fits an airlock. Even after you wedge all this junk into it, it still fits a carboy neck! Use this in any configuration you can think of, it'll fit: Airlocks, Thermowells, Racking Canes, and anything else you can imagine!

For my five gallon barrel

Needed a stopper to hold airlock and thermowell during fermentation in a standard 6.5 gal glass carboy.

Hoping this will allow for temperature probe to read beer temp instead of ambient fermentation chamber temp.

PRETTY good for thermowells
I used this on my glass carboy so I could insert both an airlock and a thermostat sensor / thermowell. Both airlock and thermowell fit with no issue - but I did have a little more difficulty in getting the stopper to stay put inside the neck of the carboy. When wet, I had no luck - the neck had to be extra dry. BUT, once in, it didn't pop out again. Recommended!
