FAQ: CO2 refills in Kentucky

Do suppliers in Kentucky 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.
