Speidel replacement part means good quality
Good idea to keep a spare stopper on hand.

Just like the original - it's a perfect fit. Fits much better than the stoppers fit into glass carboys (this one never pops back out)

Nice stopper
This is just for the red stopper, not the entire stopper/airlock combo. Nice quality

Fits perfectly in Erlenmeyer flasks
This rubber bung fits perfectly in the 2L Erlenmeyer flask found in the yeast starter kit. I use the Speidel fermentors, so using the same airlock for the yeast starter is just one less thing I have to worry about.

classic airlock
I personally dislike airlocks like this, too many moving parts. No harm in the classic S-shape.
