FAQ: CO2 refills in Tennessee

Do suppliers in Tennessee refill customer-owned CO2 cylinders?
Some do, some don’t. Many prefer exchange programs because it’s faster and reduces liability. Always ask: “Do you refill customer-owned CO2 (CGA-320)?” before driving.
What’s the difference between refill and exchange?
Refill means they fill your exact cylinder. Exchange means you swap yours for a full one (often quicker). If you’re getting turned away, exchange is usually the easiest path.
What valve/connection do I need for standard CO2?
Most CO2 tanks use CGA-320. If your setup is for kegerators/aquariums/paintball, you may need an adapter or specific regulator. If you’re not sure, start with the Guides page.
What should I ask before I drive across town?
Ask: refill vs exchange, customer-owned policy, tank size limits, appointment rules, and whether they stock CO2 for your use-case. Policies can change, and “we used to” is not the same as “we do.”
How do I get a listing updated or verified?
If you own a listing, use Claim to request changes. Verified listings can be ranked higher and can include a custom image once you have one.

Before you drive across town

Ask these questions

  • Do you do refill, exchange, or both?
  • Do you fill customer-owned cylinders?
  • Do you support CGA-320 (standard CO2)?
  • Any tank size limits or appointment rules?
