Original Spare Parts & Re-arming Kits for All Inflatable Lifejackets
An inflatable lifejacket is critical personal life-saving equipment that requires regular inspection and dedicated maintenance. Over 95% of inflatable lifejackets worldwide utilize standardized inflation mechanisms from one of three leading manufacturers: United Moulders (UML), Halkey-Roberts (HR), or Hammar. Bövik Marin AB provides fresh original re-arming kits, replacement CO₂ gas cylinders, cellulose bobbins, and safety clips compatible with leading brands such as Baltic, Spinlock, Mullion, Crewsaver, Helly Hansen, Plastimo, Regatta, and many more.
Quick Guide: Selecting the Correct Re-arming Kit
- 1. Identify the firing head on your lifejacket: Open the lifejacket cover and locate the markings on the operating head.
- United Moulders (UML): Most commonly MK5 (all-black/green cartridge), Pro Sensor, or Pro Sensor Elite (featuring red/green status indicators).
- Halkey-Roberts (HR): Typically Alpha Auto or Pro 1F systems utilizing an internal yellow bobbin (V80040) and a green indicator clip.
- Hammar: Hydrostatic systems (such as Hammar MA1 / A1) triggered by hydrostatic water pressure, replaced using a dedicated opener key.
- 2. Check the cylinder size (weight in grams): Ensure the gas cylinder matches your lifejacket's buoyancy rating (Newtons):
- 33 grams CO₂: Standard for 150N – 165N lifejackets (most common adult recreational size).
- 38 grams CO₂: Designed for 170N – 190N offshore vests (e.g., selected Spinlock and Baltic models).
- 60 grams CO₂: Engineered for heavy commercial 275N – 300N work vests.
- 3. Standard Marine Threading: All our CO₂ cylinders feature standard 1/2"-20 UNF threading to guarantee universal fitment with compliant inflators.
Annual Inspection & Bobbin Replacement
Water-activated bobbins and dissolving cartridges carry an expiration date. They should be replaced every 2 to 3 years for leisure use, or annually for commercial marine operations in damp environments.
