Fill with water and insert in drilled stopper or bung to vent gases during fermentation. Includes body, piston, and vented cap. This airlock is easy to disassemble and clean out in the event of a blow-off.
Works as intended
This airlock works great and I prefer this over the S shapes airlocks because they are easy to clean
Should have bought more than one.
Did exactly what it is supposed to do. Easy to clean. Easy to use.
