The Hop Bong is a versatile pressurizable tri-clamp accessory, capable of not only dry hopping oxygen purged hops into fermenters, but also as an inline carbonation/oxygenation accessory.

This upgrade kit is for existing FermZilla Tri-Conical and All Rounder Fermenter users that already own the Plastic Pressure Kit with 2x Ball Lock Caps and Floating Dip Tube. If you already own these pieces, then you just need the two accessories below for a complete Hop Bong Pressure Pack.

  • Tri-Clamp Pressure Lid
    • Replacing the standard lid with the FermZilla Tri-Clamp Pressure Lid provides you with a 2" T.C. port at the top of your fermenter. This will give you an opening to add dry hops or other additions without needing to remove the entire lid. Take off the butterfly valve to add your yeast pitch, and when you're ready to add flavoring additions when fermentation is complete, drop them in oxygen-free via the Hop Bong. PCO1881 threaded ports are there for your Ball Lock Caps, as well as undrilled ports for an optional Thermowell and/or Temp Twister cooling coil.
  • Hop Bong 
    • Load up the Hop Bong and add CO2 to purge your hop charge of oxygen. This kit comes with a Ball Lock Cap to introduce CO2 directly to the Hop Bong, as well as a pull ring PRV to release pressure and purge oxygen. Once you've flushed your hop charge with CO2, open the butterfly valve to inject your beer with up to 6 oz of hop pellets.

Hop Pellet Capacity: 150–180g (5.2–6.3 oz)

Kit Includes:

  • FermZilla 2" T.C. Pressure Lid Starter Kit
  • 2" Hop Bong
  • 2" FermZilla Tri-Conical Butterfly Valve
  • Red PRV & PCO1881 Cap Combo
  • Red Ball Lock Cap
  • (2) 2" Tri-Clamps
  • (2) 2" Silicone T.C. Gaskets

Does Not Include:

  • Yellow Ball Lock Cap
  • Secondary Red Ball Lock Cap
  • Floating Dip Tube with Filter Attachment

KegLand Part Number: KB10921


Warning: Always depressurize your system COMPLETELY before removing fittings from your fermenter.

Are you able to remove the hop bong above the valve and still maintain pressure in the fermzilla? Assuming valve remains closed of course.
Robert Leap on Oct 28, 2022
BEST ANSWER: As long as you leave the valve in place you can remove the rest of the assembly without relieving pressure from the main tank. You will want to be careful to release the pressure from the sight glass portion of the hop bong before undoing the clamps that hold it in place. After closing the valve, simply depress the center poppet on one of the ball lock connectors to relieve the pressure before disassembling.
Can I use this to also add liquid extracts oxygen free?
William Daffern on Feb 18, 2023
BEST ANSWER: You should be able to. You'd need to have the cylinder purged of O2 (either by fermentation while keeping the butterfly valve open OR feeding the cylinder via the QD with CO2 while venting O2 out the relief valve); then you would feed your liquid through the QD into the cylinder, venting CO2 if the pressure rose enough to prevent your liquid from flowing. Once you have your extract loaded all you would have to do is open the butterfly valve (carefully - there may be unequal pressures on either side) to allow it to flow down into the main chamber.
Does this fit former versions of the Fermzilla or just the tri-conical?
Chris Garrett on Feb 27, 2024
BEST ANSWER: It works for both. You have to have the right lid for it Enter an answer to this question.
Cant you just do the same thing from the of the tri conical????
Matt Mcdonald on Apr 25, 2023
BEST ANSWER: I try not to dry hop on top of disturbed or active yeast so if you clean it out then add hops it would work. But this way. You can dump hops in 24-72 hrs then dump it all at once
is ther a place for a temp probe in the cap like the original cap does ?
david silva on Feb 25, 2023
BEST ANSWER: Yes, you need to drill it out, it’s a bit of a tight squeeze because of the way it’s designed. I installed a temp probe in mine.

Works Great
Just used it to dry hop for the first time and it works great. Fermented under 5 psi with the valve closed. Opened up the hopper and put in 7oz of pellets (that's about as much as it will fit). Closed it up, purged with co2 and opened the valve. Had to move the handle back and forth to work the hops down, but they went down super easy. It's a little pricey in comparison to the fermenter itself, but it's made dry hopping easier than opening it up like before.
