Life Jackets & PFDs: CO2 Rearm Kits, Hydrostatic Valves & Inspection Rules

An automatic inflatable life jacket without proper maintenance is a false sense of security. Follow these critical maintenance protocols:

1. Match the Exact Gram Weight of the CO2 Cylinder

  • 24-Gram Cylinder: Typically delivers 22.5 lb buoyancy (rated for small adults / calm water).
  • 33-Gram Cylinder: The tournament standard, delivering 35 lb buoyancy—enough to flip an unconscious, fully clothed angler in boots face-up within 5 seconds!
  • Never interchange 24g and 33g cylinders—the thread pitch (1/2" vs 3/8") and air bladder volume are engineered strictly for one size.

2. Green-Means-Ready Inspection Window

  • Inspect the indicator window before every boat launch. Both the cartridge indicator and manual lever pin must show SOLID GREEN.
  • If any indicator is RED, the cylinder has been fired or loosened. Replace with the manufacturer's official Rearm Kit immediately.

3. Service Life of Water-Sensing Bobbins & HIT Inflators

  • Yellow Bobbin (水溶药片): Replace every 2–3 seasons. High humidity degrades the starch disc.
  • Hydrostatic HIT Caps: Features a 5-year expiration date stamped right on the cap. Replace upon reaching the date even if the green indicator is visible.
