When it comes to life-saving equipment, there’s no room for compromise. As the owner of a CO2 cartridge factory with 5 production lines and global export capacity, I’ve helped countless buyers—from marine safety suppliers to OEM inflator brands—find the right source for life jacket inflation cartridges. With our factory based in China, we’ve served clients across Europe, the US, Southeast Asia, and beyond, offering fully customized, safety-tested CO2 solutions.
In this ranking, I’ll walk you through 8 globally recognized CO2 cartridge brands that serve the life jacket and personal flotation device (PFD) market. These are companies I’ve either worked with, researched extensively, or carefully benchmarked against in our production and quality testing. The list is unordered, but I’ll start with our own brand—Alizeemetal—for context.
Alizeemetal

At Alizeemetal, we manufacture threaded CO2 cartridges specifically tailored for life jackets and inflatable PFDs. Each cartridge is leak-tested, weight-controlled, and designed for smooth puncture activation—crucial during emergencies. We support 33g, 38g, and 60g sizes, with precision threads like 1/2″-20 UNF and M18x1.5. OEM buyers can add their own branding, batch engraving, and even choose packaging kits with inflators.
Our edge lies in complete in-house production and quality control. We don’t just outsource—we own the tools and test every batch ourselves. That’s why major marine gear suppliers in Europe and Australia trust us as a consistent factory partner.

With ISO 9001 certification and batch traceability, LELAND ensures each cartridge meets marine safety regulations.
What sets them apart is their deep integration with inflator systems and strong presence in US-based safety standards. If your focus is the US coast guard or military supply chains, LELAND is a top-tier option to consider.

(No official website found)

Although B.MARINE doesn’t maintain an official website, its CO2 cartridges and inflator kits are frequently bundled with OEM life jackets in Asia and the EU. Their cartridges usually come pre-installed and certified for single-use activation.
Buyers working with B.MARINE should verify cartridge compatibility before sourcing replacements. While their product is common in ready-made life vests, they do not appear to focus on standalone CO2 supply for wholesale buyers.
AMScuD

Main Products: Scuba gear, diving accessories, CO2 cartridges
Other Products: Buoyancy compensators, snorkels, wetsuits
Dive Deeper:
AMScuD is a reputable Southeast Asian brand, and its catalog includes CO2 cartridges for automatic inflatable life jackets. They serve both retail and OEM buyers, focusing on affordability and regional distribution across Indonesia and Southeast Asia.
Their cartridges are often bundled with inflator systems in their own life jackets, rather than sold as standalone OEM items. Still, for distributors in Southeast Asia or companies looking for regional partners, AMScuD offers accessible pricing and functional quality.
Mustang Survival
Location: Canada
Company Type: Premium marine safety manufacturer
Founded: 1967
Number of Employees: ~150
Main Products: Inflatable PFDs, dry suits, CO2 inflatable vests
Other Products: Workwear for marine, fishing, and rescue professionals
Dive Deeper:
Mustang Survival is a premium brand with a strong reputation in commercial fishing, naval, and offshore industries. While they don’t manufacture CO2 cartridges directly, their life jackets rely heavily on proprietary CO2 inflation systems.
Their cartridges are usually private-labeled or sourced from top-tier manufacturers, paired precisely with each vest model. For B2B buyers, this brand sets the gold standard in safety compliance and product performance, though it’s less ideal for raw cartridge procurement due to closed-system design.
Crewsaver
Location: United Kingdom
Company Type: Marine safety and survival brand
Founded: ~1957
Number of Employees: —
Main Products: Inflatable life jackets, CO2 rearming kits
Other Products: Liferafts, flares, marine clothing
Dive Deeper:
Crewsaver, part of the Survitec Group, is one of the most recognized names in marine life-saving gear. Their life jackets are widely used in professional sailing, offshore, and leisure marine markets.
Their rearming kits include CO2 cartridges (24g, 33g, 38g) and compatible firing mechanisms. Though their CO2 supply is often OEM-sourced, the brand’s market reach and packaging quality make them ideal for buyers who need cartridges paired with inflators or sold as branded kits.
Secumar
Location: Germany
Company Type: Life-saving equipment manufacturer
Founded: 1926
Number of Employees: —
Main Products: Inflatable PFDs, rearming kits with CO2
Other Products: Survival suits, emergency accessories
Dive Deeper:
Secumar offers some of the most rigorously engineered life jackets on the market. German-made and SOLAS-compliant, their products cater to naval authorities, commercial fleets, and advanced water sports.
Secumar’s CO2 cartridges are typically built into their inflator kits, with a strong emphasis on precision activation and reliability. They rarely sell loose CO2 cartridges separately, but if you are sourcing complete systems or rearming kits, they offer premium performance worth the investment.
Halkey-Roberts
Location: United States
Company Type: OEM inflator and valve systems manufacturer
Founded: 1941
Number of Employees: —
Main Products: Life jacket inflator mechanisms
Other Products: CO2 valves, medical check valves, gas control devices
Dive Deeper:
Halkey-Roberts is not a CO2 cartridge manufacturer but a global leader in inflator systems that use cartridges. Their mechanisms are used by dozens of PFD brands worldwide.
If you’re an OEM buyer or life jacket brand developing your own inflatable model, choosing a Halkey-Roberts inflator means you’ll need compatible cartridges—usually 33g threaded. They publish strict guidelines for cartridge compatibility, and their systems dominate the B2B inflator supply market.
Final Thoughts
Whether you’re supplying inflatable life vests to commercial fishing crews or assembling rearming kits for marine brands, understanding the cartridge source matters. Some brands focus on performance and branding, while others (like us at Alizeemetal) specialize in the OEM and bulk supply side.
I always recommend starting with your target use case:
- Need price-per-unit efficiency and customization? Go with factory suppliers like us.
- Need integrated systems and retail kits? Look into Mustang, Crewsaver, or Secumar.
- Need inflator mechanisms? Start from Halkey-Roberts and build backward.
Each option in this list fills a different part of the value chain—and knowing the difference gives you the edge.
