Among their many products and services? CO2 tanks and refills. 

Ace Hardware carries 12-gram paintball cartridge refills in their stores. If you have a gas-powered pistol, you can also buy some CO2 here. Depending on the size of your tank, a refill could cost between $5-$22. 

You can drop by their physical stores for a refill, or go to their website to buy their products.

Most branches offer 10-pound to 60-pound CO2 canisters, with select branches offering even bigger alternatives. You can then have these tanks filled at the store immediately after purchase.

Tank refills for a small 5-pound CO2 cartridge will cost about $15. Refills for larger tanks will range from $12-$50 depending on the size. If you decide to buy a bigger tank, their empty tanks available for sale range from $100-$500.

If you’re planning on buying a tank, you can always go to their physical stores or visit their website to purchase. Of course, tank refills are only available in-store.

3. Dick’s Sporting Goods

A refill for 12-oz. and 20-oz. cartridges will cost you $34 and $5, respectively. You can also sign up for their “Aim for Five” program to get every fifth refill for free. The store, however, doesn’t allow refills for bigger sizes.

Walmart has CO2 tanks for sale. It sells 8-gram to 90-gram tanks, 60-liter SodaStream cylinders, and 20-ounce paintball tanks. 

While Walmart doesn’t offer in-store refilling of your CO2 tanks, it allows you to exchange an empty tank for a pre-filled one. This will cost you about $13-$30, depending on the size. 

You also have the option to buy empty tanks through their online website.

5. Other Locations

If none of the stores listed above are near you, it might be better to find a local business that offers CO2 tank refills. Examples of businesses that provide these kinds of products and services include: 

  • Welding supply stores
  • Paintball fields and paintball stores
  • Fire equipment supply stores
  • Hydroponics shops

CO2 tank refills in these locations typically cost $10 to $20 for smaller tanks. Some offer tank refills, while others only let you exchange used tanks for pre-filled ones. 

As much as possible, make sure to call these local stores before you visit so you can make sure that they offer refills there. 

What Are the Uses of CO2? 

Carbon dioxide or CO2 has a ton of everyday applications. Some of its most well-known uses are in:

  • Air-conditioning and refrigeration systems
  • Paintball gun cartridges
  • SodaStream machines
  • Home-brewing
  • Inflation of wheels, pools, etc.
  • Fire extinguishers
  • Freshwater aquariums

Other lesser known uses of carbon dioxide include its applications in treating apnea and even in helping the environment. 

CO2 is an additive to oxygen that acts as a breathing stimulant for people who have been diagnosed with apnea. It is also used as a more environment-friendly alternative in aerosols, where CO2 can function as a propellant. 

How Can You Save on CO2 Refills? 

Opting for CO2 refills is already a way to save money on your CO2 needs in itself. However, there are a few more extra tips you can follow if you want to save a few extra bucks.

  • If you can buy a large tank for your CO2 refills, go for it. It often costs less to refill bigger tanks than it does to refill smaller ones.
  • Buy equipment that you can use to transfer CO2 from your large tanks to small cylinders. 
  • Look for nearby CO2 refilling stations and compare prices before you choose which one to go to. 
  • Take note of promos and discount programs (such as Dick’s Sporting Goods’ Aim for Five program) that allow you to save money on refills. 

Conclusion

If you regularly use CO2 for your profession, hobbies, or other applications, then you know that refilling is always a better option than buying a fresh new tank every time.
