PopularGas · OEM CO₂ Cartridge Supply
Application-led sourcing for marine safety brands that need the correct fill, thread or neck, cap profile, corrosion protection, documentation and sample validation.
Built around your device, not a generic catalogue claim
Life-jacket cartridges are safety-critical components. Buyers should qualify the complete interface and inflation system rather than choosing only by a visible gram marking.
PopularGas evaluates each project against the buyer’s drawing, sample, interface, fill requirement, test plan, packaging and destination-market documentation. Final dimensions, thread, neck profile, filling tolerance and compliance documents must be confirmed on the approved specification sheet before mass production.
Typical applications
- Inflatable life jackets and personal flotation devices
- Marine workwear and rescue equipment
- Automatic or manual inflation systems
- Replacement-cartridge and rearming-kit programs
What buyers should send
- Inflator brand/model or technical drawing

Life-jacket cartridge RFQ checklist
PopularGas can review common fill ranges, but an approved device match requires the buyer’s interface information.
| Device | Life jacket, PFD, rescue buoy or related inflator |
|---|---|
| Fill requirement | Common projects may reference 24g–60g; confirm exact requirement |
| Interface | Thread/neck, sealing face, puncture profile and cap |
| Environment | Salt spray, storage, temperature and humidity expectations |
| Packaging | Individual protection, rearming kit or bulk OEM pack |
| Documents | Request the model-specific available test and transport package |
A practical OEM qualification workflow
- Application review: share the device, deployment scenario and destination market.
- Interface confirmation: provide a drawing, dimensional checklist or physical sample.
- Specification approval: agree fill weight, thread or neck, tolerances, finish, marking and packaging.
- Sample validation: test fit, puncture or activation behavior, leakage and device performance.
- Mass-production release: approve the golden sample and required inspection/document package.
Frequently asked sourcing questions
Which cartridge size should I choose for a life jacket?
Use the life-jacket or inflator manufacturer’s specified cartridge. Do not substitute by gram size alone.
Can you match a thin cap or special neck?
Send a drawing or physical sample. The cap, neck and puncture geometry can then be reviewed.
Can cartridges be supplied as part of a rearming kit?
Packaging and kit requirements can be discussed after the approved model and destination market are confirmed.
How should compatibility be stated?
State only the inflator models validated by your own testing; avoid universal compatibility claims.
