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!

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

Solid for the Anvil fermenter.
Prefect fit for the anvil fermenter. Love the rubber material. Not too thick so your airlock breaks when you pull it out and not so thin that the thermowell just slowly slips out.

Handy for airlock and temp probe
Bought this for my small batch gallon carboys. Fits very nicely and accomodates my airlock and the temperature probe for my temperature managment system.

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!
