Ferroday Carbonation Keg Lid + Diffusion Air Stone & Tubing – $24.59 + free shipping

FERRODAY Carbonation Keg Lid Cornelius Keg Lid Soda Beer Forced Carbonation Homebrew Carbonator Stainless Steel 304 Carbonation Keg Lid with Diffusion Stone 20" Tube - Oval Keg Lid

Ferroday Ball Lock Carbonation Lid with Diffusion Stone

More Info

From the product description, check product page for current description, price and availability:

  • 【Includes All You Need】Keg lid + Air stone + 20 inch tubing; All the metal parts are made of SS304, the head of the pressure release valve is made of solid ABS, food safe tubing, gaskets, all sturdy and wear-resistant.
  • 【Widely Used for Home Brew】 Widely used to carbonate beer, soda, juice, water and even sparkling water. Fits to all the homebrew kegs that require a standard oval lid, normally called: corny keg/cornelius keg/ ball lock keg…This is a perfect choice for keg lid replacement!
  • 【Best Carbonation & No More Shaking】Forced Beer Carbonation: the diffusion stone will send a tremendous number of gas bubbles out through the beer and the miniscule bubbles will create a huge amount of surface area to help absorb CO2 rapidly into the beer! No need to shake the keg during carbonation anymore!
  • 【Safe Pressure Release & Cleaning Tips】 1. For safety concerns, the valve will automatically open up when pressure in the keg reaches 70 psi; 2. Please release the pressure in keg before open the keg. 3. Please clean the kit before and after each use, and please note the diffusion stone needs to be boiled in water to unclog pores.

 

This has a ball lock post on it that has in inlet on the inside of the keg. That inlet connects to tubing which in turn connections to a carbonation stone. This should work on standard ball lock and pin lock kegs, although you’ll need a ball lock QD to connect to it.

How do these work?  My theory… CO2 is dispersed through the stone into solution. This causes a small amount of movement in the liquid, this movement helps to the solution to come to equilibrium more quickly than simple head space pressure. I’m not saying this is a steady flow of bubbles, my guess is a slow, periodic occurrence, enough to speed up the process. This is a theory.

Hands on Review: Ferroday Stainless Steel Carbonation Cap for PET Bottles & Draft Line Cleaning Builds

This is a hands on look at a Stainless Steel Carbonation Cap by Ferroday along with some information about what these are used for and some related build projects.

What are stainless steel carbonation caps used for?

  • PET Bottles as Growlers: These are generally intended to convert 1L and 2L bottles to growlers.  Fill up a 1L or 2L PET bottle with your favorite homebrew.  Put one of these on (purge the headspace by squeezing if you want to) and then pressurize for transport.  This should help to reduce oxygen pickup and maintain carbonation levels.
  • Fine tune or rapidly carbonate beer: You can also use this cap to rapidly carbonate beer.  Same process as for transport, just set your regulator to the proper pressure and shake or agitate the PET bottle to help introduce CO2.  Or hook it up to CO2 and let it sit in you kegerator.
  • Draft Line Cleaning Projects:  I have developed three draft line cleaning projects using similar SS Caps – Build A Recirculating Draft Line Cleaning Pump | Mark II Keg and Carboy Cleaner Draft Line Cleaning Pump Conversion | Building a Simple Ball Lock Draft Line Flushing Setup

Universal Liquid and Gas Carbonation Caps

The really big question that needs to be answered, if you want to build a draft line cleaning setup using one of these, is whether or not it is universal.  Ball Lock Kegs have gas and liquid posts along with corresponding QDs.  Black goes on liquid, grey or white goes on gas.  They ARE NOT interchangeable.  The beauty of some stainless steel carbonation caps is that they are universal, meaning they can accept both gas and liquid QDs.  That’s very important for draft line cleaning builds because we want to connect a liquid QD to this.  The problem is, not all stainless steel carbonation caps are universal.

Kegland DuoTight Inline Secondary with Gauge! control each keg separately & more – $14.44 via DuoTight Sale + Hands on Review

Duotight Regulator with Gauge

Duotight Regulator with Gauge via William’s Brewing

More Info

From the product description, check product page for current description, price and availability:

This 8mm Duotight compatible regulator with 0-60 PSI gauge fits 8mm outer diameter EvaBarrier tubing. Suitable for gas, all components are food grade. The included gauge is accurate to plus or minus 6 PSI.

Note: This unit comes with a 0-60 PSI gauge that is only ¾” in diameter. If you intend to use this regulator in the 10 to 30 PSI range, you will need to order optional gauge C93, which reads 0-30 PSI. Below 10 psi, this regulator is not very accurate. You will also need EvaBarrier tubing to connect this regulator, either our item number Z91 or Z92.

This is perfect for reducing the pressure of one gas line in a draft system – for example, with a single regulator and C02 bottle, you can set the pressure at the C02 bottle with the larger regulator (not included) and then put this regulator inline to reduce the pressure. Handy for when you want to carbonate one keg at 25 PSI and dispense another at 10 PSI.

Top Content Countdown… Our 3rd Most Popular Resource Post of 2021!… Build a Spunding Valve! – How and Why

A Spunding Valve allows you to maintain a set pressure.  If pressure in the vessel exceeds the set point, it is expelled.  It generally consists of an adjustable PRV valve, a tee, a gauge and a way to connect to your keg.

Homebrewing Applications of a Spunding Valve

  • Pressurized fermentation.  Ferment in a 5 or 10 gallon corny keg and use your Spunding Valve instead of an airlock.  This allows you to ferment at your desired pressure.
  • Dry hop under pressure.  This allows you to dry hop earlier while reducing oxygenation.  Active yeast are more likely to metabolize oxygen that’s introduced during dry hopping during active fermentation.  Since CO2 is not exiting beer as vigorously under pressure, wanted compounds, flavors and aromas are more likely to stay in your beer under pressure.
  • Naturally and accurately carbonate beer right in the keg.
  • An airlock replacement.  Keep the valve wide open for non-pressurized fermentations.  Only do this if you have plenty of head space.  This wouldn’t make a great blow off tube.
  • Keg to keg transfers.  Use the Spunding Valve to allow excess gas to exit the receiving keg as you transfer under pressure.  Helps you achieve a slow, controlled and pressurized transfer.
  • Fix over-carbonated beers.
  • Test for keg leaks.  Pressurize your keg to serving pressure.  Put the Spunding Valve on (with the pressure set well above your serving PSI) and note the reading.  The gauge should remain steady.  If pressure drops, you know you have a keg leak.  The digital build, see below, is especially helpful for this task,  The digital gauge reads with .1 PSI resolution making pressure changes easy to spot.  It’s worth noting that this checks the entire keg including gas body o-ring.  That spot is hard to check and other way as it’s only in function when the gas QD is on.  When the gas QD is on… it’s difficult to spray and check for bubbles underneath the gas QD.  Thanks to Scott Janish for this tip!
  • As an airlock for long term aging of beers.  Airlocks can run dry over time.  A Spunding Valve will not.
  • Utilize CO2 from fermentation for flushing kegs and fermenters.
