The carboy & bottle washer creates a jet-style stream that penetrates build-up in bottles or carboys.
It is automatically activated when a bottle is pressed down onto the unit.
Female hose thread connection.
The faucet adapter allows you to hook up the Bottle & Carboy washer to most kitchen sink faucets ( NOT all the kitchen sink faucets ).
Some faucets will work better with brass instead of stainless because the softer metal will conform to the existing threading better.
