Seachem Bottle Adaptors Small

Seachem Bottle Adapter Plugs come in two sizes and allow you to seamlessly connect dosing pump tubing to any Seachem or Aquavitro bottles ranging from 50 mL–1 L and many other common supplement bottles (24 mm–28 mm) on the market. 

Simply insert a plug into the bottle neck of your supplement of choice, then insert tubing into its opening. Once inserted, this connection will also help to prevent spillage in the event of a container tipping over. Be certain that the tubing runs to the bottom of the bottle.
