Airlock extension Brass for tank Lid - ID 32mm OD 42mm

A brass airlock extension for a tank lid. It gives you extra height on the lid for fitting an airlock. It also creates additional height for the airlock's water seal, helping maintain optimal protection for your wine, beer, cider, or other fermented products.

Sold as one piece in brass. Measure the opening in your lid before ordering, since the fit comes down to those two diameters.
