Frequently Asked Questions (FAQ)

What Is A CO2 Tire Inflator?

If you are an avid cyclist, you have at one time found yourself stuck due to a tire pressure emergency.

If you are lucky enough, you can just carry your bike to the nearest bike shop but what if you are nowhere near such a facility?

A bike pump is an essential item when riding but the problem comes in carrying bulky pumps. Such items hamper a smooth riding experience and make it less comfortable.

This is the problem a CO2 pump solves effectively. These are lightweight and portable tire inflation equipment which will come in handy in case of a flat or low tire emergency on the road.

The CO2 tire inflator setup has two pieces; a CO2 cartridge which holds the gas and an inflator also called a nozzle.

There are some bike tire inflators with flow control meaning it is possible to stop air flow while others don’t.

The CO2 cartridges come in different sizes such as 12 g, 16 g or 25 g with smaller ones designed to fill tires up to 90 PSI and larger ones up to 120+ PSI.

These CO2 canisters can either be threaded or non-threaded types. In case you need to use your pump, you just need to get the inflator/adaptor head, screw it onto the cartridge and then direct the inflator onto the valve of the bike tire. When you twist (for threaded cartridges) or push down (for non-threaded cartridges) you are able to instantly transfer the pressurized CO2 from the cartridge into the tire.

It is a fast inflation option and the cartridge is for a single use. The inflator will be used over and over again and for this reason you need to buy a sturdy and durable product.

These CO2 bike tire inflators are small, compact and lightweight and for this reason, you can carry them around without affecting the quality of your ride. If you don’t like carrying your frame pump around, it is time you buy a portable and highly efficient CO2 bike tire inflator.

How Does a CO2 Tire Inflator Work?

A CO2 inflator is a very convenient solution to inflate your bike tire in case of an emergency. It is a handy item that you should always have in your backpack or saddle bag. CO2 bike tire inflators are lightweight portable alternatives to the bulky frame pumps in the market.

The fact that tire pressure affects quality of your ride makes a bike pump an essential every rider should have. The only problem is that bicycle pumps are weighty and hamper a smooth ride. A CO2 inflator deals effectively with this problem. If you are planning to buy one of these bike tire inflators, it is important to understand how they work.

There is a small canister inside which CO2 is compressed. You need an inflator/nozzle to transfer the CO2 into the tire tubes. The cartridge is for one-time use meaning you have to get it right the first time. Here are the steps to follow to use your CO2 inflator correctly:

  • Check the tube and confirm there are no punctures or sharp objects on the tire.
  • Ensure the valve is in the open position before connecting anything. Clear any debris from the valve for effective tire inflation.
  • Take the inflator from its storage bag and confirm it is closed. If open make sure you close the valve all the way.
  • Thread/push the cartridge in the inflator. This is an important task in using your CO2 tire inflator correctly. The head and cartridge should thread easily.
  • Tighten the cartridge into the valve stem. The tube will pierce the end of the cartridge end. The trigger on the inflator is the one that allows the compressed CO2 to immediately escape into the tire tube. Remember once the cartridge is pierced, there is no going back and if you try removing it, you will lose a cartridge for no reason.
  • Hold the inflator’s head unit carefully onto the valve stem and now open the air flow by operating the trigger which could be a dial or button. For your safety, wear gloves because the cartridge will be extremely cold and that’s why some models come with a sleeve bags for protection.
  • Close the valve on the cartridge and carefully pull off the inflator. Replace the valve cap if any.
