38mm Stainless Ball Lock Carbonation Cap – on sale for… $3.49, save 77%

38 MM Stainless Steel Ball Lock Carbonation Cap

More Info

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

An all stainless male gas ball lock cap that fits 38mm plastic PET growler bottles. This allows the PET Growler to be charged with C02 from any female ball lock gas fitting (like our item D32 or D03 Gas Connector), carbonating the cold beverage in the bottle including cold water. Cap threading is industry standard 38-400 growler threading.

This is ideal for adding a bit of charge to a PET growler after you fill it, as no matter how carefully you fill a PET growler from a draft system, some C02 carbonation is lost. Great for serving draft beer away from the keg. For use with plastic bottles only. Note: This does not fit PET bottles with standard PICO thread, like our item I12.

WARNING! Always wear eye protection. For use with plastic bottles only. Never exceed 20psi carbonation pressure.

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.

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.

Build a Recirculating Draft Line Cleaning Pump + New Safecid Beer Line Cleaner Review (toward end of review)

Clean kegerator lines are a key part of serving delicious beer. Bacteria and mineral build in lines can cause off flavors, quick loss of head, under-carbonated beer due to rapid co2 loss and lack of legs forming on the inside of your beer glass.


Limited Time Deal:

Helps you clean multiple lines at the same time…

Valuebrew is offering a pack of two jumpers and 25 replacement o-rings for $32.97. Coupon code JUMP discounts the combo by a whopping 32%.

Double Jumper Special! < note that you must use this link along with coupon code JUMP to get the deal, the standard product will not get you the discount

Valuebrew’s jumper is unique because of the custom color, food grade o-rings and because … it works with both liquid and ball lock jumpers.


The directions on most line cleaners call for recirculating the cleaner for some period of time.  Most affordable cleaning setups that are out there include a hand pump.  Operating one of those for 15 to 30 minutes, for each faucet, doesn’t sound fun.

To really clean your draft lines, you need to keep solution flowing for a length of time, not just fill and wait.  Initially I tried to clean my system by pushing line cleaner out of a keg.  This was a waste of CO2.  I also found it tough to keep solution running slowly enough to get the required amount of contact time.  It’s easy to quickly push a cleaning or sanitizing solution through your system under CO2 pressure, but I found it to be a pain to try to do so slowly.  This also requires quite a bit of cleaning solution versus a recirculating pump.

I decided to put together a recirculating draft line cleaning pump setup.
