Buying Guide
- What marker compatibility should I check? Confirm cartridge type (12g vs 88/90g, threaded vs non-threaded) and whether an adapter is required for your marker model.
- Which size is right for me? Choose 12g for quick, light usage or 88/90g for longer sessions without frequent changes. Consider game length and transport convenience.
- Are prefilled cartridges better? Prefilled options save downtime and ensure immediate use, but verify compatibility with your marker and any required adapters.
- Gas quality and valve health—how important? Higher-purity CO2 helps maintain valve integrity and consistent power, reducing performance fluctuations over time.
- Cost and availability considerations? Bulk packs offer lower per-cartridge cost but require storage and organization. Ensure you can securely store CO2 and prevent leaks.
- Safety and storage tips? Store in a cool, ventilated area away from heat sources and direct sunlight. Inspect cartridges for dents or leaks before use.
Frequently Asked Questions
- What CO2 cartridge size should I start with for paintball? Start with 12-gram cartridges for casual play or experimentation, or 88/90-gram cartridges for longer sessions with fewer changes.
- Do I need adapters to use 90g CO2 cylinders? Some markers require adapters; check your marker’s manual or manufacturer guidance before purchasing the 90g option.
- Are there risks using non-threaded 12g cartridges? Non-threaded designs are common, but ensure your marker supports non-threaded CO2 and inspect seals to avoid leaks.
- Is CO2 quality important for performance? Yes. Higher-purity CO2 reduces valve buildup and improves consistency, especially with frequent firing.
- Can I reuse CO2 cartridges? Most CO2 cartridges are single-use; reuse is not recommended due to potential leaks and safety concerns.
- What should I do if I notice leaks? Stop using the cartridge immediately, reseat connections, and replace the cartridge if a leak persists. Do not attempt to force-fit incompatible cartridges.
