Speidel Grommeted Airlock Cap


Using your existing Speidel lock ring and gasket this airlock cap screws right into the lid of your Speidel plastic fermenters. The grommet will fit standard 3-Piece or S-Shaped airlocks. The cap also provides a tighter seal because it is screwed into the cap where as the Speidel stopper only pushes into the lid.
