Overview
Japanese-manufactured fire extinguishers have a well-earned reputation for precision engineering and long service life — a reflection of the manufacturing standards applied across Japanese industrial production. Yamato Protec and Hatsuda are two of Japan’s most established fire extinguisher manufacturers, with their equipment widely specified on Japanese-built vessels, offshore installations, and commercial and industrial facilities across Asia and globally. Both brands produce cartridge-operated dry powder extinguishers where a CO2 propellant cartridge drives the extinguishing agent discharge — and like all cartridge-operated extinguishers, these units require the correct replacement CO2 cartridge at each service interval to maintain their operational status.
The challenge is specificity. Japanese extinguisher manufacturers use cartridge specifications that are distinct from European and Asia Pacific standards — with thread types, body dimensions, and gas charge weights defined to their own manufacturing specifications rather than to a shared regional convention. The thread standard used across Yamato and Hatsuda extinguisher models — referenced as YAMATO · HATSUDA across the cartridge range — is the correct specification for these brands, and using a cartridge to a different thread standard risks improper seating, puncture failure, or gas leakage that renders the extinguisher non-functional.
These Original CO2 Cartridges for Japanese Fire Extinguishers are 100% Made in Japan replacement propellant cartridges for Yamato Protec and Hatsuda cartridge-operated extinguishers — available across nine cartridge models covering the full range of Yamato Protec MODEL 10, MODEL 15, MODEL 20, YP-10NR, YP-15NR, YP-20NR, and Hatsuda extinguisher types. With IMPA codes published for key variants, these cartridges support the procurement documentation requirements of the international marine supply system — a concrete differentiator for vessel operators and marine procurement teams working within IMPA-referenced supply chains.
Key Features
100% Made in Japan — Original Manufacturer Specification
These cartridges are manufactured in Japan to the original specification of the Yamato Protec and Hatsuda extinguisher models they service — not aftermarket alternatives produced to an approximated specification. For safety-critical extinguisher components where dimensional accuracy, gas charge precision, and material quality directly affect actuation reliability, original Japanese manufacture provides the specification assurance that aftermarket alternatives cannot. For vessel operators and facilities managers maintaining Japanese-brand extinguishers to the manufacturer’s service standard, original Japanese-made cartridges are the appropriate replacement component.
YAMATO · HATSUDA Thread Standard — Correct for Both Brands
The cartridges are manufactured to the YAMATO · HATSUDA thread standard — the specific thread specification used across Yamato Protec and Hatsuda cartridge-operated extinguisher models. This thread standard is common to both brands, simplifying cartridge sourcing for facilities and vessels carrying a mix of Yamato and Hatsuda extinguishers. Correct thread specification ensures proper seating in the cartridge holder, reliable puncture on actuation, and a gas-tight seal in the charged condition — the three performance requirements that determine whether a cartridge replacement results in a fully functional extinguisher or a maintenance risk.
Nine Cartridge Models — Full Coverage of Yamato and Hatsuda Extinguisher Range
The cartridge range covers nine model variants — A60G, A120G, B12.4, B30, B38, C30, C60, N2 CO2 D61, and N2 CO2 13.4 — providing replacement cartridge coverage across the full range of Yamato Protec MODEL 10, MODEL 15, MODEL 20, YP-10NR, YP-15NR, YP-20NR, and Hatsuda cartridge-operated extinguisher models. For ship managers and procurement teams maintaining Japanese-built vessels with mixed Yamato and Hatsuda extinguisher inventories, the breadth of model coverage means the complete extinguisher service requirement can be addressed from a single cartridge supplier and a single procurement transaction.
IMPA Codes Published for Key Variants — Marine Procurement System Compatibility
Three cartridge variants carry published IMPA (International Maritime Purchasing Association) codes: B30 (IMPA 331050), C30 (IMPA 331032), and N2 CO2 D61 (IMPA 331059). IMPA codes are the standard product identification system used across the international marine supply chain — referenced in vessel purchasing systems, ship chandler catalogues, and procurement platforms used by ship managers, technical superintendents, and vessel procurement officers globally. Published IMPA codes for these cartridge variants allow direct procurement by IMPA reference number, supporting accurate ordering, inventory management, and procurement documentation for vessel operators working within IMPA-referenced supply systems.
Covers Yamato Protec MODEL 10, 15, 20 and YP-NR Series
Yamato Protec’s MODEL 10, MODEL 15, MODEL 20, YP-10NR, YP-15NR, and YP-20NR are among the most widely specified Japanese cartridge-operated dry powder extinguishers on Japanese-built commercial vessels, offshore platforms, and industrial facilities. The NR (Nitrogen Rechargeable) series in particular is a common specification on Japanese-built ships where cartridge-operated extinguishers are part of the original equipment fit. Cartridge coverage across this range ensures that the most common Yamato Protec extinguisher types encountered in the field can be correctly serviced from this cartridge range without requiring alternative sourcing for specific model variants.
Suitable for Annual Service and Post-Discharge Recharge
CO2 cartridge replacement is a required task at each annual service inspection and following any discharge of a cartridge-operated extinguisher. For fire safety service contractors, vessel maintenance crews, and facilities maintenance teams servicing Yamato Protec and Hatsuda extinguishers across Asian port calls, regional drydocks, and industrial maintenance programmes, local Singapore availability of the correct Japanese-specification cartridges supports on-schedule service completion without the lead times and sourcing complexity of procuring directly from Japanese distributors.

Benefits
Original Japanese manufacture eliminates the specification uncertainty of aftermarket alternatives. When a Yamato Protec or Hatsuda extinguisher is serviced with an original Made in Japan cartridge, the service is completed to the manufacturer’s specification — with dimensional accuracy, gas charge weight, and material quality consistent with the original component. For vessel operators and facilities managers who need confidence that their extinguisher inventory is genuinely serviceable — not just visually compliant — original manufacture is the appropriate standard.
IMPA codes enable direct procurement by reference number — no manual cross-referencing required. For procurement officers and technical superintendents working within IMPA-referenced vessel supply systems, the published IMPA codes for B30 (331050), C30 (331032), and N2 CO2 D61 (331059) allow these cartridge variants to be ordered directly by code — eliminating the manual model cross-referencing that slows procurement of non-coded components and reducing the risk of ordering errors when procuring under time pressure during a port call.
Full model range coverage from a single supplier simplifies fleet-wide cartridge procurement. Japanese-built commercial vessels frequently carry mixed Yamato Protec inventories — different extinguisher model types across different vessel spaces, with different cartridge requirements for each. The nine-model cartridge range covering all major Yamato Protec and Hatsuda variants means the complete cartridge requirement for a vessel’s extinguisher service can be addressed in a single procurement transaction with Alright Engineering Solutions, rather than sourcing different cartridge models from multiple suppliers.
Singapore local availability eliminates Japanese supply chain lead times for regional operations. Japanese-built vessels calling at Singapore and Southeast Asian ports, and offshore installations operating in the regional oil and gas sector, frequently carry Yamato Protec or Hatsuda extinguishers as original equipment. Sourcing replacement cartridges through a Singapore-based distributor avoids the lead times and freight costs of procuring directly from Japanese suppliers — particularly important for vessels with limited port turnaround time and for offshore installations with tight maintenance windows.
SOLAS and class society service compliance supported by original-specification component replacement. Portable fire extinguishers on SOLAS-regulated vessels must be maintained using components appropriate to the manufacturer’s specification. Replacing CO2 cartridges with original Japanese-made components for Yamato Protec and Hatsuda extinguishers supports the documented maintenance standard required for class society survey compliance and port state control inspection — where extinguisher service records are routinely reviewed under the Tokyo MOU, Paris MOU, and other regional PSC inspection frameworks.
Who It’s For
The Technical Superintendent at a Japanese Shipping Company or Ship Management Firm
You manage the maintenance programme for a fleet of Japanese-built bulk carriers, tankers, or car carriers — many of them originally outfitted with Yamato Protec MODEL 15 or YP-15NR extinguishers across accommodation areas, engine rooms, and cargo spaces. Extinguisher service and CO2 cartridge replacement is a recurring maintenance task at each vessel’s annual service visit. You need a reliable regional supplier who stocks the correct Yamato and Hatsuda cartridge models — including IMPA-coded variants that can be ordered directly through your vessel purchasing system — and who can confirm availability and turn around a supply quotation within the timeframe that vessel port scheduling demands. Alright Engineering Solutions’ Singapore stock of Japanese-specification cartridges with published IMPA codes supports exactly that procurement workflow.
The Marine Safety Equipment Contractor Servicing Japanese-Built Vessels
You carry out fire extinguisher service on Japanese-built vessels calling at Singapore — a significant and consistent part of your workload given Singapore’s position on major Asia-Europe and transpacific shipping routes. When you board a Japanese vessel for extinguisher service, the Yamato Protec and Hatsuda units on board need the correct original-specification CO2 cartridges to be serviced correctly. Your ability to complete service on first visit — rather than returning with the right cartridges after a supply delay — depends on having reliable pre-port access to the correct Japanese-specification cartridge models from a local supplier. Alright Engineering Solutions’ nine-model range covering all major Yamato and Hatsuda variants gives you that supply confidence.
The HSE Officer or Maintenance Manager at a Japanese-Built Offshore Platform or Industrial Facility
Your installation was constructed in Japan or outfitted with Japanese fire safety equipment, and the Yamato Protec or Hatsuda extinguishers across your facility need annual service. You’ve had difficulty in the past sourcing the correct Japanese-specification cartridges locally — generic alternatives were suggested but you were uncertain about dimensional compatibility and specification compliance. Alright Engineering Solutions can confirm the correct original Japanese cartridge for your specific Yamato or Hatsuda extinguisher models and provide a formal quotation for a service schedule or stock order, without the uncertainty of aftermarket alternatives.

Original CO2 cartridges manufactured in Japan for Yamato Protec and Hatsuda extinguishers reflect the same manufacturing standard as the original components — providing dimensional accuracy, gas charge consistency, and material quality appropriate for safety-critical extinguisher components. “100% Made in Japan” is not a marketing claim but a specific, verifiable statement of country of manufacture with direct implications for component specification and quality assurance.
Yamato Protec — Established Japanese Fire Safety Equipment Manufacturer
Yamato Protec Corporation is one of Japan’s leading fire safety equipment manufacturers, producing fire extinguishers, fire detection systems, and suppression equipment for domestic and export markets. Yamato Protec extinguishers are widely specified on Japanese-built commercial vessels, offshore installations, and industrial facilities — making them among the most commonly encountered Japanese-brand extinguishers in the international marine and offshore maintenance market. Original replacement CO2 cartridges for the Yamato Protec MODEL range and YP-NR series are the manufacturer-appropriate service components for these widely deployed extinguisher models.
IMPA — International Maritime Purchasing Association Product Coding
The IMPA (International Maritime Purchasing Association) product coding system is the standard procurement reference used across the international marine supply chain — referenced by ship managers, vessel purchasing officers, and ship chandlers globally for the identification and procurement of marine equipment and consumables. IMPA-coded products can be ordered by code reference number through vessel purchasing systems, reducing procurement errors, supporting inventory management, and enabling price comparison across multiple suppliers. Published IMPA codes for three cartridge variants (B30: 331050, C30: 331032, N2 CO2 D61: 331059) make these the most straightforward cartridge variants to procure through standard vessel purchasing workflows.
SOLAS Chapter II-2 and Tokyo MOU Compliance Support
SOLAS Chapter II-2 requires portable fire extinguishers on commercial vessels to be maintained in serviceable condition and serviced at required intervals. The Tokyo MOU port state control inspection framework — covering ports across the Asia Pacific region including Japan, China, South Korea, Singapore, Australia, and their maritime neighbours — routinely inspects fire fighting equipment condition and service records. Japanese-built vessels operating in the Tokyo MOU region are among the most frequently inspected vessel types; maintaining Yamato Protec and Hatsuda extinguishers with original-specification CO2 cartridges supports the service standard required for PSC compliance and Tokyo MOU inspection.
