Josh uses carbonator caps to assist with closed transfer racking to kegs.  If you look at the photo he shared, he’s putting a small length of tubing on the cap and then feeding that through the airlock grommet hole of his fermenter.  This same process could be adapted to work with other styles of fermenters.

Although it doesn’t matter a whole lot for this application, I recommend looking for a model that’s compatible with your intended application that works with both gas/grey and liquid/black QDs. This will give you maximum flexibility.
