Buyer's Guide

The CO2 Inflator has two crucial parts which are C02 Cartridge and the head. They are made up of a small metal cylinder filled with CO2. The flat tire is filled up with compressed CO2. You are supposed to purchase a valve per 2 cartridges though some come with two cartridges in the package.

They are designed differently as they have the activated, controlled inflators, pushing to expand and twist to inflate. Whenever you buy a CO2 inflator always make sure you have chosen the correct Inflator by making sure you look at the right material, the correct size of the head and quality type of Inflator.

Which CO2 inflator to use

Inflators come in two different materials which include plastic or aluminium. If you are on a strict budget, then opt for plastic inflators, but they are not durable compared to the aluminium inflators. CO2 inflators that are too small might be portable to carry around but will be challenging to use. Therefore, opt for inflators that are usable despite the size as stability in use is essential.

CO2 cartridges have two different types which include the non-threaded and the threaded ones. The threaded cartridges are expensive but easy to use as compared to the non-threaded, which are cheap. The non-threaded are popular but not long-lasting as the threaded cartridges. The cylinder of the non-threaded inflator protects you from the cold temperature during the flat tire's inflation.

Specs of the CO2 inflator

The CO2 inflator weighs about 16g and easy to carry around with you as it can fit in a small bag. It is coated with aluminium and has fibre. The inflator has a stylish look as it comes in various outstanding colours. The inflator's nozzle has many different colours, such as silver, red, black, blue and purple. These colours are eye-catching and of high definition. The inflator head fits all CO2 cartridges of 25g, 20g, 16g and 12g. Mainly the affordable inflator heads can only fit in 12g and 16g. Always make sure to know if your inflator head is compatible with many cylinder tanks. Some tanks are bought separately from the head inflator.

Easy to use

Luckily the inflator is compatible with any valves hence easy to use. The CO2 cartridge has a shielded sleeve which aids in preserving the temperature to keep the CO2 even. The inflator's nozzle contains a one-turn valve system that makes it easy for you to quickly release the CO2 into the flat tire then once full, you quickly close the valve.

The inflator is useful as it fills a flat tire in seconds as compared to the bike pump which takes ages to fill up the tire. Its control lever makes it easy for you to control the pressure of the CO2 into the bike. Always note that the CO2 inflator is an essential element to carry with you at all times as it saves you from being stranded with a flat tire and energy as it is effortless.

The good thing about CO2 inflators is that they need you to inflate compressed pressure into the flat tire whilst a normal pump requires you to pump air into the flat tire. What a fun way to get a job done without an effort. These inflators are durable as they can allow you to use half of a cartridge and use the remaining cartridge next time you face the same problem.

Inflators are a temporary solution to your flat tire as the compressed pressure can allow you to get to the nearest garage without damaging your tire. These Co2 inflators are affordable to invest in as they come with two cartridges and a valve nozzle.


The worst thing that could happen to you is getting stuck with a flat tire in the middle of nowhere without a solution. Manually pumping the tires can be time-consuming. It is not the ideal option for an emergency. Always make it a point to carry your CO2 inflator as it saves you time and instantly inflates your flat tire in seconds. I hope this article has helped you understand the need to have an inflator and use the inflator. Purchasing the correct sized head and cartridge will help you easily use the CO2 inflator with no hustle. Enjoy a smooth ride with no worries about a flat tire as a CO2 inflator gets you covered.
