## 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)
