The Challenges of Sourcing 16g Threaded CO2 Cartridges for the USA Market
Import managers and brand owners often face these hurdles when procuring small CO2 cartridges:
- Thread mismatch: Non‑standard threading can cause gas leaks or failure to seal in branded dispensers.
- Inconsistent gas fill weight: Some suppliers under‑fill cartridges, leading to shorter use times and customer complaints.
- Compliance uncertainty: 16g threaded CO2 cartridges sold in the USA must meet DOT/UN pressure vessel regulations and be free of harmful contaminants.
- Long lead times & high minimum quantities: Many factories require MOQs of 100,000+ units, which is too high for new product launches or mid‑sized importers.
- Poor packaging protection: Cartridges arrive dented or scratched due to inadequate packaging, hurting your brand image.
Our Solution – 16g Threaded CO2 Cartridges Engineered for the North American Wholesale Market
We have developed a dedicated production line for 16g threaded CO2 cartridges specifically for B2B clients in the United States. Every cartridge is manufactured from cold‑drawn steel, then internally cleaned and helium‑leak‑tested before filling. The threaded neck is machined to a tolerance of ±0.002 inches to guarantee a secure fit with industry‑standard dispensers (e.g., Sodastream, iSi, and generic soda siphons).

Real Customer Reviews
Mark T. – Import Manager, Texas Distributing Co.
"We switched to XingYe's 16g threaded CO2 cartridges six months ago. The thread fit is perfect on our soda machines – zero leaks. Their QC reports on every pallet give us confidence. Lead time was 18 days on our first 100k order."
