Senior Airlock - three piece airlock designed to be easy to clean. This unit has a main body, which is used to house a small amount of liquid. There is a floating cap which sits over the hose in the middle of the main body. Finally there is a lid which holds the floating cap in place and creates the bubbling action.

Has a slightly larger external diameter fitting than the standard Vintage S-shaped airlocks, but is still compatible with standard fermenter grommets and bored bungs.
