An all stainless male gas ball lock cap that fits 38mm plastic PET growler and Tap A Draft bottles. This allows the PET Growler or Tap A Draft  bottle 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. 

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. 


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

Works perfectly on my growler and Tap A Draft
Makes it easy for me to charge my growler so it does not go flat. Also fits my Tap A Draft.

Lost the silicon gasket for this cap. Do you have a replacement I can buy? Thanks......
Sorry, we do not have these

Will this fill a stainless growler (prokeg)? If not, do you sell an adapter that I can carbonate stainless growlers tonabout 10-15 psi?
This will not fit since it is threaded, we do not have anything that fits this style of opening.

I'm carbonating in a large bottle at 40psi and then transferring to smaller bottles so slight leaking is acceptable (and I think my 28mm carbonation cap leaks slightly). I'm not storing with the cap. Sounds like this should work for my needs then?
This item is rated at 20 PSI or less, so it would not work in a 40 PSI application.

Why is it 20psi max? Because of the bottle? Or can the cap itself not handle more? If coupled with a higher pressure bottle can it go higher? I'd like to use it for 40psi soda water. Wondering what could go wrong since my 28mm cap works fine at 40psi.
Over 20 psi, the poppet in the cap may leak, so we cannot recommend using this at 40 psi.
