Paintball CO2 tanks and accessories are still used in specific paintball setups, especially with older mechanical markers, paintball pistols, and recreational backyard play. While compressed air has become the standard for most modern paintball markers, CO2 remains a practical option in certain situations when used correctly.
CO2 is stored as a liquid inside the tank and expands into gas when fired. Because of this, performance can vary based on temperature and rate of fire. CO2 works best with markers that are designed specifically for it and in moderate weather conditions with slower firing rates.
When CO2 Makes Sense
CO2 can be a good choice for players using basic mechanical markers, paintball pistols, or markers designed specifically for CO2 operation. It is commonly used for backyard play, casual recreational setups, and situations where compressed air fills are not readily available.
Disposable CO2 cartridges are also widely used in paintball pistols and mag fed markers, where portability and simplicity matter more than sustained fire or shot consistency.
CO2 Tanks and Cartridges
Standard refillable CO2 tanks are available in common sizes such as 20oz and are designed for markers that support CO2 use. Smaller disposable cartridges, including 8g and 12g options, are single use and are commonly used in paintball pistols and compact setups.
Always verify that your marker is CO2 compatible before using a CO2 tank or cartridge. Many modern markers are compressed air only and can be damaged if CO2 is used.
CO2 Tank Accessories
Accessories play an important role in protecting and improving CO2 tank setups. Tank covers and grip tape help prevent slipping and improve control, especially since CO2 tanks can become cold during use. Thread protectors help prevent damage to tank threads during transport and storage.
These accessories extend the life of your equipment and make CO2 setups more comfortable and reliable to use.
CO2 Frequently Asked Questions
Can CO2 be used on compressed air markers?
No. Most modern paintball markers are designed for compressed air only. Using CO2 can cause pressure and temperature related issues that may damage internal components.
Can CO2 tanks be refilled?
Yes. Larger CO2 tanks such as 20oz bottles are refillable. Disposable CO2 cartridges like 8g and 12g canisters are single use and cannot be refilled.
Is CO2 better than compressed air?
Neither is universally better. Compressed air offers more consistent performance and is preferred for most paintball markers. CO2 is best suited for specific markers, pistols, and casual setups where simplicity and portability are priorities.
