If you are an Import Manager or Sourcing Agent looking for reliable threaded CO2 cartridges for the US market, you need a partner who understands DOT-39 regulations, precise 5/8-18 UNF threading standards, and high-volume logistics. At XingYe Chemical, we provide engineered CO2 solutions backed by a 8,000m² factory, 80+ skilled technicians, and over a decade of expertise in gas filling and container manufacturing.
The Sourcing Challenge: Why Quality & Compliance Matter in 2026
The US market for threaded CO2 cartridges is highly regulated. Brand Owners and Wholesalers often face three critical pain points:
- Inconsistent Threading: A mismatch in UNF threads can lead to gas leaks, wasted product, and damaged dispensers.
- Compliance Risks: Non-DOT certified cartridges can result in shipping bans and liability issues.
- Supply Chain Delays: Long lead times from smaller factories disrupt inventory for wholesale distributors.
These problems cost the industry thousands in losses annually. The solution lies in sourcing from a vertically integrated factory with strict quality checks and global shipping expertise.
Engineered Precision: Our Threaded CO2 Cartridge Portfolio
At XingYe Chemical, we manufacture high-strength threaded CO2 cartridges designed for soda water machines, paintball markers, industrial pneumatic tools, and emergency inflation devices.

Application-Specific Sourcing Tips for Threaded CO2 Cartridges
Different end-use cases require specific technical considerations. Here is how we tailor solutions for each market segment:
- Food & Beverage (Soda Water): Requires food-grade 99.99% pure CO2 with 5/8-18 UNF threading. We provide non-toxic, oil-free cartridges to ensure perfect carbonation without off-flavors.
- Paintball & Airsoft (Powerlets): Demands high-pressure 88g/90g tanks with reinforced threads to withstand rapid fire. Our 6061 aluminum models are leak-proof and lightweight.
- Industrial (Pneumatics): Needs consistent pressure dispensing. Our steel 16g and 20g threaded cartridges are engineered for quick gas discharge in industrial settings.
- Emergency & Safety (Life Jackets): Requires absolutely reliable sealing and corrosion resistance. We use a double O-ring system in our threaded valves to ensure zero gas loss.
Why Import Managers Choose XingYe Over Generic Suppliers
