Hydrostatic Inflator Technology

How HIT™ Works

Hydrostatic pressure is applied to objects submerged in water. The hydrostatic inflator needs only to be submerged 4 inches (10 cm) or more for the hydrostatic pressure to open a pressure valve releasing a firing mechanism, automatically inflating the PFD.

HIT™ Advantages:

  • Low maintenance – no inflator maintenance required for five years, unless fired.*
  • Reliable inflation – inflated only under hydrostatic pressure or by pulling the manual activation cord. Will not inflate due to rain, humidity or water contact.
  • Easy to see safety inspection window – Easily view the inflator replacement date and inflator status through the safety inspection window. Green indicates ready for use.
    *Inflator is maintenance-free for 5 years from date of manufacture. Upon inflation, it is essential to inspect and re-arm your PFD before next use.
