The Vintage Shop

Double Bubble S-Type Airlock


This Double Bubble S-Type Airlock from The Vintage Shop allows your fermentation to vent without letting contaminants in. Works for both winemaking and home brewing.  This is a 6.75″ plastic airlock and the sound they make is kind of a blip-blip-blip unlike the 3-piece airlocks that go bloop-bloop-bloop.

  • Made in Canada.
  • Made of soft, BPA-free plastic.
  • Comes assembled with the snap on cap.
  • Snap on cap, makes it more difficult to lose.
  • Cap with holes on top, making it easy to breathe.
  • Small chambers allow you to check for pressure differences between the fermenter and outside.
  • Fits the 38 mm screw cap.
  • Rounded stem at the bottom, making a better seal when working with rubber bung.
  • Maximum Temperature: 60 °C (140 °F).
