Jaybird™ Krausen Catcher with 4 Nipples

for Ball, Kerr, or Mason Wide-Mouth Jar

304 Stainless Steel


One-of-a-kind Krausen Catcher for your fermenter is the ultimate airlock replacement / blow-off tube!

  • Ever experience a crazy fermentation where krausen plugs your airlock or blow-off tube?
  • Ever check on an airlock and find (gasp!) that it has dried out? Or worse yet… back-flushed into your fermenting wort?
  • Ever have a blow off tube slip out of the blow off container (and therefore out of sanitizer solution)?
  • Ever have the blow-off container dry out of sanitizer solution - or get knocked over - exposing the blow-off tube to room air (and all the junk that floats in it)?

The Krausen Catcher fixes ALL those issues by providing sturdy hose attachments, a lid-sealed containment system, and the ability to attach 1/2" hoses to any of its 4 connections!

Think of this as a GIANT 3-piece airlock… with all of the benefits and none of the draw-backs!

All you need is a couple of feet of 1/2" inner diameter tubing and a wide mouth Kerr, Ball, or Mason jar (sold separately) in the 16, 32, or 64 ounce size.

DAISY CHAIN THIS WITH OUR GROMMETED VERSION OF THE KRAUSEN CATCHER (SKU# 2840) to create a CO2 harvesting, back flow-preventing airlock (see SKU# 3210, and the video below).


  1. Fill a wide-mouth canning jar (not included) with the proper amount and mix of sanitizing solution
  2. Place a length of tubing over one of the “inside” nipples of the Krausen Catcher. Tube length should be long enough to “almost” reach the bottom of the canning jar once canning jar lid is attached to jar.
  3. Place Krausen Catcher on canning jar and tighten the canning jar’s lid over the Catcher
  4. Attach a half-inch inner diameter hose over the same-side outside nipple on the Krausen Catcher
  5. Run the other end of the hose to the CO2 exit port of your fermenter


  • 304 Stainless Steel
  • 1/2" inner diameter tubing connects to any of the 4 nipples
  • Works with any “wide mouth” (3-inch inner opening) Ball, Kerr, Mason or equivalent canning jar
