Onyx A-33 In-Sight Re-Arm Kit

The Onyx A-33 In-Sight Re-Arm Kit is the certified replacement cartridge system for Onyx Automatic In-Sight Inflatable Life Jackets. This re-arm kit restores full deployment capability to A-33 series vests after inflation has been triggered, ensuring operators and maritime professionals maintain mission-ready equipment without purchasing an entirely new jacket.

The kit contains a 33-gram CO2 cylinder paired with a Halkey-Roberts bayonet assembly—the standard quick-connect fitting used across Onyx's inflatable life jacket lineup. This pairing ensures reliable, instantaneous gas transfer to the bladder upon activation. The included water-soluble bobbin dissolves on water contact, triggering automatic inflation in immersion scenarios. At 0.4 lbs and compact pocket dimensions (6 x 2 x 8 inches), the cartridge integrates seamlessly into vest storage without adding significant weight to your load-out.

This cartridge is essential for maritime patrol, water-based tactical operations, and any duty profile where personnel operate near or over water and rely on redundant flotation systems. Coast Guard, Navy, and commercial maritime crews depend on re-arm kits to extend service life of A-33 jackets through multiple deployment cycles—eliminating the cost of full jacket replacement after a single inflation event. The 33-gram CO2 volume is engineered specifically for the A-33 bladder capacity, delivering full flotation buoyancy on demand.

Onyx Outdoor manufactures to ISO 12402 standards for personal flotation devices, ensuring cartridge pressure and volume tolerances meet maritime safety specifications. Verify your jacket model before purchase—the A-33 In-Sight Re-Arm Kit is engineered exclusively for Onyx A-33 Automatic models and is not compatible with other brands or Onyx jacket series.
