By James Miller | Senior Sourcing & Compliance Specialist | Updated: 2026
If you are an Import Manager or Brand Owner searching for a reliable source of threaded CO2 cartridges that meet US DOT/UN safety standards without sacrificing margins or lead times—you have reached the right partner. At Zhuzhou XingYe Chemical Co., Ltd., we have spent over a decade perfecting the filling technology for high-pressure gas cartridges. Our threaded CO2 cartridges serve the paintball, culinary, automotive, and wellness industries. We combine China’s supply chain efficiency with rigorous ISO 9001:2015 quality systems to deliver exactly what your business needs: purity, precision, and packaging flexibility.

Why Consistency in Threaded CO2 Cartridges Defines Your Brand
In the B2B wholesale market, threaded CO2 cartridges are a high-volume commodity where reputation is built on two critical factors: gas purity and thread integrity. Leaking cartridges or impure gas (containing moisture or hydrocarbons) can destroy expensive equipment—from paintball markers to soda siphons—and damage your brand’s credibility.
Common procurement pain points we help resolve:
- Inconsistent Fill Weights: Some suppliers under-fill to cut costs, causing customer complaints.
- Cross-Threaded Necks: Poor machining of the 5/8"-18 UNF thread leads to regulator failure.
- Certification Gaps: Non-UN/DOT approved cartridges are illegal to transport or sell in the US.
- High MOQs: Large factories often demand 50,000+ units, tying up working capital.
- Slow Lead Times: Standard lead times of 40–50 days can disrupt your retail launch calendar.
Technical Specifications: Threading, Gas Purity, and Compliance
As a factory that originally specialized in industrial and food-grade gases, we apply the same strict standards to our threaded CO2 cartridges. Below are the standard specifications. (Note: All parameters are for reference. Final specs to be confirmed in order contract.)
