Excellent choice for a 5 gallon glass carboy fermenter. You don’t want to use the smaller airlocks because they could become clogged and blast off due to the amount of fermentation generated by the 5 gallon. The hose has to be forced into the carboy so it creates a tight seal. The exit end should be put into a small bucket or container of sanitizer. This allows the pressure to escape while still maintaining an airlock.
This thing is so stiff that it doesn’t seal in the airlock port. They claim it will seal without a bung but it doesn’t.
