Review: Great, works even better with some upgrades - When we got the carbonation lid for our corny keg, we were trying to figure out a way to provide carbonated water during the 2 days it would take to charge a fresh keg, and found these (same brand). The idea of being able to take a bog standard 2 liter bottle and charge carbonated water in it was, TBH, mind blowing, so I decided to give it a try, in the hopes it would give us a backstop while the keg recharged. The cap itself is cut on the sides allowing you to use a keg spanner to tighten it up, a really useful feature for us with physical disabilities that make grip an issue. It works so well! One thing that we did though was to get some liquid tubing, and a pair of micro porous stones (Ferroday again). We hooked the tube and stone up, in the hopes we could get the micro porous stone speed, and easier to store standing up while it charged. It works well in both cases. So for 3, 4 hours of charging, at 35psi, we get a 2 liter bottle of carbonated water. Any short of a time doesn't seem to work, but I don't know if this is a limitation of the carbonation cap or operator error, as I've seen YouTube videos that claim less than an hour to charge a bottle. I'd recommend this, both for charging a 2 liter bottle before going out, or as we're using it, to make sure we have standby fluids. If you're using this alone, rather than with the upgrades I mentioned, remember to lay the bottle on its side in the fridge for the tube to be inside the liquid.
Review: Easy to make your own carbonated drink creations - Works well. I use it to make my homemade version of Manhattan Special.

## Questions & Answers

**Q: Does it work with glass water bottles (such as pellegrino bottles)?  Thanks.**
A: NO! Don't ever try to force carbonation into a glass bottle, unless you want to be blasted with shrapnel from the bottle when it explodes! These are for plastic PET bottles only.

**Q: What size is the big flat o ring on the inside? I need a replacement for my carbonator cap.**
A: Hello,the size of the big O-ring inside are 26mm(outside diameter),18mm(inner diameter),4mm(line diameter).Thank you !

**Q: I've just got one of these, and it leaks when connected to a normal pet bottle. is this what the o-ring is for? or do i have a deffective unit?**
A: Make sure the inner metal piece..the one with the hose Barb..is tight. It screws into the main part of the cap. Also that large washer is key to getting a good seal on the bottle. Mine gets screwed down so tight that when I remove the cap it's inside the mouth of the pet bottle.

**Q: will this take both liquid and gas assemblies?**
A: Yes, you can use the liquid or gas assemblies ( liquid ball lock or gas ball lock)

### ⭐⭐⭐⭐⭐ Perfect!
*by W***D on July 6, 2024*

My local home brew store could not provide me with one of these that worked. It was plastic trash that would not work with the ball lock they set me up with. I thought maybe it was a defect and returned to see if I could get a refund or exchange, and they couldn’t get it to work either, and a new one also would not work. This one is well-built, looks good, fits on standard bottles, has no leakage, and costs less than the name brand, plastic junk.
