## Questions & Answers

**Q: Hi, do you sell with 21.8 connector instead of CGA320 ?**
A: Sorry we don't have that.

**Q: Does this regulator fit a standard CO2 tank**
A: Yes it does fit a standard Co2 tank.

**Q: Do i have to buy two if im using a splitter for two tanks or does one control both?**
A: The solenoid with bubble counter only can be used for one tank.

**Q: If the solenoid is not making a clicking sound does that mean it’s not working? C02 will not come through.**
A: Possibly. If you've eliminated the cord and the outlet then it's going to be a problem with the solenoid.
