Replaces the oversized airlock that comes with our Speidel plastic tanks.
Does Not include the stopper shown in the photo.
Height 5 3/8". Outer diameter 2 7/8". Stem outer diameter 23/32". Stem inner diameter 9/16".
I bought this as a spare.
I prefer this airlock over the typical 3-piece plastic airlocks. It's only 2 pieces, but just as effective and easy to clean. Better design concept overall. Sturdy too. Bought this as a backup - but my original is still 100% in tact, so this one is just waiting for it's moment to shine .
This is just for the two piece airlock set, doesnt include the red stopper. Nice airlock, works with no flaws.
