## Questions & Answers

**Q: Can I use this to seal a converted sanke keg?**
A: Hello Hunter,This cap will not work on a sanke keg unfortunately. I have seen where customers use a rubber stopper to do this, but I am not sure of the size you would need. I hope this information helps you some.Sincerely,Marissa

**Q: What are the diameters of both opening? Looking at closed CO2 transfers...**
A: The bigger one has the same ID as 3/8th inch tubing, the smaller one measured at ~4/16th an inch.

**Q: Will this fit a standard wide mouth glass gallon jug?**
A: Thank you for your inquiry. The carboy caps do not fit the wide mouth gallon jugs. The carboy caps do work on a 3, 5, or 6 gallon glass carboy.

**Q: Dose this fit a 18.9 lts carboy made in Italy ?**
A: I believe that it should.  It is fairly flexible.
