Which CO2 Cartridge Size Is Right for Your Life Jackets?
Understand the differences between 17g, 24g, 33g, and 45g CO2 cartridges — and why 33g CO2 cartridges remain the industry benchmark for inflatable life jackets.
Selecting the correct CO2 cartridge ensures your inflatable PFD inflates quickly, safely, and meets regulatory requirements. Here’s how each cartridge size is typically used in the life jacket industry:
Cartridge Size | Best Used For | Why It Matters |
17g CO2 cartridges | Youth life jackets, SUP vests, basic recreational PFDs | Lightweight option with minimal buoyancy (50–100N); ideal for compact vest models |
24g CO2 cartridges | Belt-pack PFDs, adult recreational boating vests | Low-profile with sufficient fill for 100–120N; popular in warm-weather regions |
33g CO2 cartridges | CE 150N-rated inflatable life jackets, universal adult safety gear | The most used cartridge for adult PFDs; works with Halkey-Roberts and UML systems |
45g CO2 cartridges | Offshore rescue jackets, commercial and industrial marine PFDs | Delivers full inflation for high-buoyancy (275N+) vests in emergency scenarios |
✅ Why Most Buyers Choose 33g CO2 Cartridges
If you’re sourcing CO2 cartridges for adult inflatable life jackets, 33g CO2 cartridges are almost always the first choice. They’re the standard size for 150N PFDs in Europe, Australia, and many U.S. markets — and they’re compatible with most inflator systems on the market.
Whether you’re supplying a life vest brand, a rescue equipment distributor, or a marine safety retailer, 33g cartridges offer maximum compatibility and performance with minimal procurement risk.

Life Jacket CO2 Cartridge Buying Guide
Everything Marine Safety Buyers Need to Know Before Placing an Order
From cartridge sizing and inflator matching to international shipping and quality testing — this guide helps you make informed, confident decisions as a professional life jacket supplier or brand owner.
Table of Contents
Why CO2 Cartridges Are the Standard for Life Jackets
CO2 Inflation Is Instant, Manual Blowing Isn’t
When someone falls into the water, they may be unconscious, panicking, or in cold shock. A CO2 cartridge inflates the vest in under 2 seconds — reliably, even if the wearer does nothing.
Manual inflation depends on lung capacity and calm conditions. That’s not realistic in a rescue scenario.
Global Standards Require CO2-Driven Systems
Most certified life jackets — whether CE 150N, ISO 12402, or SOLAS-grade — are designed around pre-filled CO2 cartridges, triggered by manual pulls or water-activated bobbins. Manual-only systems don’t meet compliance in most commercial or regulated use cases.
Uniform Performance, Every Time
A 33g cartridge delivers the exact amount of gas needed to inflate a 150N PFD — no more, no less. No human inflation can match this repeatability, especially under stress or in freezing conditions.
CO2 Cartridges Are the Industry Standard — By Design
Over 90% of inflatable life jackets on the market — including CE 150N and ISO 12402-certified models — are built specifically for CO2 cartridge activation. This is not just about convenience, but about design compatibility, testable performance, and compliance with marine safety regulations.
If you’re sourcing for OEM production, rental fleets, or maritime contracts, CO2 cartridges are not an option — they’re the format your equipment is built around.
What Buoyancy Rating Does Each CO2 Cartridge Size Support?
CO2 cartridges for inflatable life jackets must be selected according to the required buoyancy output. Below is a technical reference table based on international usage:
CO2 Cartridge Size vs. Flotation Capacity
CO2 Cartridge Size | Approx. Buoyancy (N) | Typical Application |
17g | ~80N | Youth vests, slim waist belts, small PFDs |
24g | ~110N | Belt-pack inflatable vests (adult recreational use) |
30g | ~130N | Intermediate vests (non-standard regional models) |
33g | 150N | CE-certified adult life jackets (global standard) |
60g | 275N | Commercial & offshore rescue jackets, SOLAS-level PFDs |
Buyer Notes:
- 33g is the most commonly used CO2 cartridge size for global marine-standard inflatable life jackets.
- 24g is typically used for low-profile belt-type PFDs; not suitable for offshore or industrial use.
- 60g cartridges are required for high-risk scenarios where 275N buoyancy is mandatory (e.g. offshore, SOLAS).
💡 Inflation performance also depends on inflator design and bladder size. For OEM validation, we recommend test-fitting with your specific life jacket model.
Send us your vest or inflator model — we’ll confirm specs and recommend a validated option.
How Does a Life Jacket Inflator Work? CO2 Inflation Trigger Mechanisms Explained
Inflatable life jackets rely on a life jacket inflator — a mechanical device that holds and pierces the CO2 cartridge to release gas into the air bladder. This system is the core of every CO2-based inflation process and is designed to activate through one of the following methods:
1. Manual Activation
The wearer pulls a cord, which triggers the inflator’s internal piercing pin to puncture the threaded CO2 cartridge. This action rapidly releases compressed gas to inflate the life jacket.
- Used for: kayaking, boating, fishing — where the wearer is conscious and water exposure is frequent
- Advantage: avoids unintended inflation during rain or splashing
- Note: requires user action; not suitable if unconscious or incapacitated
2. Automatic Activation (Water-Activated)
The inflator contains a water-soluble bobbin that dissolves upon immersion. Once dissolved, the piercing mechanism releases, activating the CO2 cartridge automatically.
- Used for: offshore safety gear, commercial vessels, rental fleets
- Advantage: activates even if the wearer is unconscious
- Variants:
- Standard bobbin type: activates on direct water contact
- Hydrostatic inflator: detects water pressure, reducing false activations in heavy rain
3. Dual Activation System
Most modern inflatable life jackets combine both manual and automatic triggers in a dual inflator system.
- Allows automatic inflation upon submersion
- Includes manual backup via pull handle
- Standard for CE 150N / ISO 12402 / SOLAS-compliant PFDs
Inflator System Components Include:
- A life jacket inflator head with a piercing mechanism
- A compatible CO2 cartridge (e.g., 33g for 150N buoyancy)
- A bobbin unit or hydrostatic sensor (for automatic versions)
- An indicator clip or firing status window
- A manual pull handle with safety pin
Choosing the correct inflator-compatible CO2 cartridge (thread type, neck length, fill weight) is critical for safety and performance.
How to Safely Store Life Jacket CO2 Cartridges in Wholesale Operations
CO2 cartridges used in inflatable life jackets are classified as pressurized gas containers and must be handled and stored according to safety standards — especially when shipped or stocked in bulk.
Here’s what every marine safety distributor or life jacket brand should know:
Storage Guidelines for Life Jacket CO2 Cartridges (Wholesale Scale)
- Store in a dry, well-ventilated environment Avoid exposure to humidity, direct sunlight, or enclosed heat zones. Indoor warehouses with ≤ 45°C (113°F) ambient temperature are recommended.
- Keep away from ignition sources and flammable materials Although CO2 is non-flammable (Class 2.2), cartridges are under high pressure and should be stored away from sparks, welding zones, or fuel.
- Organize by batch and date code Life jacket CO2 cartridges are marked with production lot numbers and expiry dates. Always apply FIFO (first-in, first-out) stock rotation.
- Avoid stacking heavy loads directly on cartons Use standard pallets and avoid compressing master cartons to prevent deformation or accidental activation.
- Store with compatible accessories Keep inflators, bobbins, and indicator clips in the same controlled area. Avoid mixing with unrelated gas products (e.g., N2O, soda CO2).
⚠️ Important for Marine Safety Products:
Life jacket CO2 cartridges are often part of regulatory or tender-based supply chains. Improper storage can affect:
- Product certification validity
- Inflator compatibility (due to corrosion or seal degradation)
- End-user safety in rearming kits
For complete storage specifications by region, DG classification details, and container stacking instructions:
How to Import Life Jacket CO2 Cartridges from China
Life jacket CO2 cartridges are classified as UN1013 – Class 2.2 non-flammable gas and must follow international regulations for dangerous goods export.
When importing from China, you’ll need to ensure:
- DG-compliant packaging with Class 2.2 labeling
- Full documentation: MSDS, COA, UN certificate, commercial invoice, packing list
- Shipment via sea freight with DG-certified forwarders (FOB Ningbo or Shanghai)
- Coordination for customs clearance and port handling on arrival
We also support bundled shipments with inflators, water-soluble bobbins, and indicator clips to streamline sourcing and reduce freight costs.
Why You Shouldn’t Choose the Cheapest CO2 Cartridges for Life Jackets
As a factory specializing in life jacket CO2 cartridges, we understand the pressure buyers face — balancing price, safety, and performance. But here’s the truth:
In marine safety, a failed CO2 cartridge is more than a product defect — it’s a life at risk.
Unlike CO2 cartridges used in bicycles or soda makers, those used in inflatable life jackets must deploy instantly, completely, and reliably. That’s why not all “cheap” cartridges are equal — and why cutting corners can cost more in the long run.
Factory Quality Checklist: What Actually Affects Safety and Performance?
Critical Factor | Why It Matters in Life Jackets | What We Do at Alizeemetal |
Gas Fill Volume & Pressure | Underfilled cartridges may not fully inflate the jacket — risking flotation failure | Precision filling to ±0.1g, verified by weight-based batch logs |
Internal Steel Cleaning | Residue, oil or rust can damage inflators or cause premature leakage | Full degreasing + air-drying for all life jacket cartridge shells |
Threading Accuracy (1/2” UNF) | If the cartridge can’t screw into the inflator smoothly, it may not seal or fire correctly | CNC-machined threads + real inflator-mount fitting check |
Post-Production Thread Testing | Ensures every cartridge still fits the inflator after plating & sealing | 100% pass-through with Go/No-Go thread gauge |
Seal Closure & Crimp Quality | A weak crimp may lead to slow gas leaks during storage or transport | High-pressure crimping + camera-based inspection |
Surface Plating (Zinc/Nickel) | Prevents rust in humid, saltwater environments | Applied after leak testing, not before |
Leak & Burst Resistance | Verifies pressure safety and deployment under emergency conditions | 100% leak-tested + 1.5× burst pressure test on every batch |
Batch Traceability | Needed for certifications, warranty claims, and import audits | Laser batch ID on every unit, matching carton and test log |
Export Packaging Protection | Avoids crushed threads, false activations or neck damage during ocean freight | Shock-resistant boxes with foam inserts and pallet wrapping |
What You May Not See in “Cheap” Cartridges:
- Threads that look right — but strip under torque
- Fill weights ±1g off spec — failing to meet CE/SOLAS buoyancy
- Coating only applied outside — rust inside neck thread
- No crimp control — small leaks after 3–6 months of shelf storage
- No batch number — making recalls impossible
- Cartons collapse in transit — arriving damaged or unsafe
These shortcuts won’t show up in price — but they’ll show up in your return rate, reputation, or regulatory inspection.
Why Life Jacket Brands Choose Us
Because they need more than a “metal can.” They need:
- Verified compatibility with inflators like Halkey-Roberts, UML, and Alpha
- Consistent inflation for 150N / 275N CE-certified vests
- Safety reports and pressure charts to pass TPED / ISO 12402 testing

Let’s make safety part of your brand — not just your bill of materials.
How to Determine If a CO2 Leak Is Caused by the Cartridge or the Inflator
When a CO2 leak occurs in a life jacket system, it’s essential to identify the correct source — whether it’s a cartridge issue or a malfunction in the inflator — before initiating replacements, claims, or returns.
Below is a focused troubleshooting checklist used by factory QA teams to help buyers and distributors make accurate assessments:
Quick Diagnostic Table: CO2 Cartridge vs. Inflator Issue
Observed Symptom | Most Likely Cause | How to Diagnose |
Hissing sound before activation, during install | Cartridge neck seal issue | Try another cartridge from the same batch — if issue persists, check the inflator |
Sudden gas release while tightening into inflator | Thread mismatch or cross-threading | Check for smooth threading; use a Go/No-Go gauge if available |
Trigger pulled, but vest doesn’t inflate | Inflator valve malfunction | Disassemble inflator and inspect for jammed spring, old O-ring, or salt residue |
Continuous hissing after activation | Partial puncture or inflator leak | Inspect piercing hole alignment and inflator valve seal |
Removed cartridge appears intact but is empty | Cartridge seal failure | Weigh the cartridge — if weight loss >10%, gas likely leaked prior to use |
Only a few units leak from a full batch | Cartridge-specific issue | Send samples and batch number to supplier for seal or plating defect analysis |
All cartridges fail across multiple inflators | Cartridge threading defect | Provide inflator model and photos — supplier can verify threading compatibility |
Recommended Diagnostic Assets:
To speed up identification and resolution:
- Provide photos of the cartridge, neck, and inflator setup
- Share a video if the leak occurred during or after triggering
- Include the cartridge lot number and purchase date
