If you are a brewer or make carbonated drinks, CO2 tanks are definitely a critical part of your business. Luckily these are readily available in multiple places online and offline. 

Ideally, CO2 tanks are steel cylinders or bottles that contain a liquefied, colorless, odorless, non-flammable, and mildly acidic gas known as carbon dioxide or carbon (ii) oxide (CO2), which has a variety of uses. While the most popular uses are in carbonated drinks and brewing beer, it can also be used in:  

  • Medicinal applications 
  • Metal production 
  • Food preservation 
  • Fire Extinguishers 
  • Kegerators 
  • Hydroponics 
  • Paintball 
  • soda-streaming devices 
  • Cycle tires 
  • Aquariums for freshwater fish and live plants 
  • Inflating sporting gear 

Where To Buy A CO2 Tank  

You can refill your CO2 tanks in several places. You can visit a welding store, any company that deals with welding machinery and air tools, or even businesses specializing in CO2 goods. You can then contact them to have the tanks delivered to your location or choose to go pick them up yourself at their premises. 

However, before you settle on a source, it is always advisable to engage several establishments to compare prices. Here are several places where you can get CO2 tanks and refills: 

1. Airgas 

Airgas has a retail network of over 900 locations across the US. It supplies tanks that come in five-pound, ten-pound, twenty-pound, 35-pound, forty-pound, 55-pound, sixty-pound, and bigger sizes. The weight of the cylinders comes when they are empty.  

Tanks may range in price from $100 to $500 or more for bigger ones. On the other hand, refills range from $15 for a five-pound tank swap to $12 to $50 or more for bigger refills. You can purchase these items at any of the store outlets or online. 

2. Ace Hardware INC. 

Ace Hardware is a major player in the home improvement industry in the United States. It is the biggest hardware retail cooperative in the world and the second largest dealer-owned cooperative in the United States. Ace has almost 5,200 hardware shops in all 50 states, and CO2 tanks and refills are among their numerous goods. 

To begin with, they sell 12-gram paintball cartridges in-store. Ace Hardware is also the best source to get CO2 for your gas-powered machinery. It costs between $5 and $22 to replenish your tank, depending on the cartridge size.  

While they are well-known for their many physical shops, and you are sure to locate one near you, you can also purchase their items via their online website. 

3. Walmart 

Walmart is one of the most famous stores in the US for selling its items at a reasonable price. The store also refills CO2 tanks, and you can request these refills using their website or Walmart’s mobile app. 

When you want to swap empty paintball cartridges for refills or soda-stream cylinders, Walmart is one of the greatest locations to purchase CO2 tanks and refills near you. They offer tanks ranging in weight from 8 to 90 grams. You may also get paintball cartridges and 60-liter soda-stream cylinders, and 20-ounce tanks for prices ranging from $13 to $30, depending on their size.  

However, you should be aware that Walmart does not have the necessary equipment to refill the CO2 tanks at its shops. Instead, you may swap your old cartridge for a new one. Nonetheless, you will be charged for the CO2 in the cartridge rather than the cylinder. 

4. Blain’s Farm and Fleet 

Blain’s Farm & Fleet has 43 retail locations in Wisconsin, Illinois, Iowa, and Michigan. It specializes in 12-grams, 88-grams, 20 cubic feet, 40 cubic feet, 80 cubic feet, and 125 cubic foot tanks and cylinders.  

The price ranges from $5 to $390, depending on the size. You can purchase it at retail outlets or order it online.

Paintball Tank Refill Near Me 

To find a paintball tank refill station near you, you can search online in various ways, such as: 

Google Search  

Try looking for “refill CO2 tanks” on your preferred search engines. You may also try googling for “CO2 refill” to see what comes up. If you’re unsure what kind of product you want to purchase, look into the many companies offering tanks and cartridges to understand how they function. 

Yelp Search  

You can also use Yelp’s search engine to search “CO2 tank refill near me”. You may discover the closest shops or dealers by following these steps: 

  • Sign in to your YELP account if you already have one. 
  • Click “search for CO2 refills near me” or “paintball tank refills near me.” 
  • Look for locations for some of the companies mentioned above and their outlets. 

Moreover, Yelp also displays user reviews for each CO2 company outlet or location. 

Stores Locator 

Shop Locators are another fantastic method to discover a CO2 store near you and are available on most official store chain websites. These platforms may be used in various ways, but the basic concept is to search for a place by zip code and obtain instructions.  

Tips for handling your CO2 tank 

Although CO2 is noncombustible, you must take specific safety measures while using your CO2 tank. For instance: 

  • Never toss or let a CO2 tank fall or store it in direct sunlight 
  • Always keep the tank upright while securing it. 
  • Keep your CO2 tank as cold as possible, preferably in a space with a temperature of around 70 degrees Fahrenheit. However, if you make them very cold, they turn into liquid. Even colder temperatures will cause them to solidify and become more concentrated or thick.  
  • Pay attention to the fill date marked on the canister’s top. If the date is five years or older, it is best to avoid using the tank. Use reliable CO2 regulators and prevent your tank from heating up rapidly. 
  • If there has been a leak from the tank, be careful to ventilate after it has been stopped, and then remove the tank right away to a Department of Transportation (DOT) -approved testing center 

Besides, using, testing, discharging, or replenishing CO2 tanks should be handled carefully; failure to do that is quite harmful. 


For whatever reason, you intend to use your CO2, refills or places of purchase are readily available. The above-covered sources are some common establishments selling or refilling these tanks.  

However, you must consider various things when purchasing the ideal CO2 tank for your needs. This may involve mobility, efficiency, and available space before deciding. Again, you should know that the material used to make the CO2 may alter the results of the project you are undertaking using the CO2. For instance, the kind of CO2 tank you have may affect the taste of your beer if you are dealing with brewing.  

You can purchase CO2 tanks from shops, hardware stores, and online. Some of these enterprises also offer additional benefits, such as gas vouchers. Consequently, you can also check for free gas near me to save on the cost of purchasing and transporting your CO2 tanks.
