CO₂ refills & tank sales in Margate
Keep your draft beer pouring and your bubbles flowing. Visit The Keg King for CO₂ tank refills, nitrogen, beer gas, and compatible SodaStream and paintball cylinder refills.
We refill 2.5, 5, 10, and 20 lb CO₂ cylinders and offer tank sales and offsite hydro testing. Call or text with your cylinder size and a photo of its valve and markings so we can confirm compatibility and availability before you visit.
Your tank. Your valve. Your stamped test date.
We refill the CO₂ tank you bring in. We do not exchange tanks—no exceptions. A refill does not renew or reset your tank’s stamped test date.
If your tank needs testing, ask about our offsite hydro testing. You can also buy a used or new tank, subject to availability.

Offsite cylinder hydro testing

Plus the cost to refill the tank. Testing is performed offsite. Leave your cylinder with us for approximately two weeks; confirm the current turnaround when dropping it off.
We will discuss cylinder eligibility and the testing service before accepting your tank. Hydro testing is not performed onsite at the store.
Tank pickup policy: Customers have 60 calendar days from the text notification sent to the phone number provided with their tank to collect it. CO₂ tanks not picked up within that period are forfeited to The Keg King for resale.
Reference: DOT cylinder requalification requirements.
Before you visit for a refill
- Tell us what you need. Include the gas type, cylinder size, and what equipment you use it with.
- Send clear photos. Show the whole cylinder, valve, and stamped markings or test date so we can discuss compatibility and any testing needed.
- Confirm service and timing. Ask about availability, the expected wait, and the total before making the trip.
Refills for your cylinder
Bring your own cylinder for refill service. Acceptance depends on the cylinder’s type, condition, markings, and compatibility. For nitrogen and beer gas, ask us to confirm the fill details for your particular tank.
