Water Sensitive Bobbin Replacement for Inflatable Life Jackets

Water Sensitive Bobbin Replacement for Automatic Inflatable Life Jackets Water-activated bobbin (yellow pill) replacement designed to trigger automatic CO₂ inflation on compatible PFD inflators. Product Description: Automatic water activation: The bobbin is designed to disintegrate when submerged, allowing the inflator’s firing mechanism to puncture the CO₂ cylinder and inflate the chamber. Compatible replacement design: Developed to match the Halkey-Roberts V80040 bobbin form factor, intended for use with compatible auto inflators such as HR V90000 (Type Alpha) and other listed HR auto systems (verify your inflator model before purchase). Reliable servicing practice: For consistent performance, replace the bobbin at manufacturer-recommended intervals and replace more frequently in high temperature / high humidity or harsh storage conditions. B2B-friendly re-arming component: Ideal as a bobbin-only replacement for maintenance, service teams, distributors, and re-arming operations (note: bobbin alone may not include CO₂ cylinder or indicator components depending on your kit needs). Correct installation matters: Install the bobbin assembly with the white pill facing the inflator cap; it should slide in smoothly when aligned correctly. Improper orientation may cause malfunction.

FAQ Q1: What does a water sensitive bobbin do in an inflatable life jacket?It’s a water-activated component that dissolves when submerged, enabling the inflator to puncture the CO₂ cylinder and inflate automatically. Q2: Is this compatible with Halkey-Roberts inflators?This is developed according to the V80040-type bobbin design and is commonly listed for HR auto inflators including V90000 (Type Alpha). Always confirm your inflator model and manual before use. Q3: How often should the bobbin be replaced?Replacement intervals vary by manufacturer and usage. Many guidance sources emphasize replacing sooner when exposed to high humidity/heat or harsh storage, and checking dates/condition regularly. Q4: Does a bobbin replacement equal a full re-arming kit?Not always. A full re-arming kit may include a CO₂ cylinder, bobbin/pill, and indicator parts depending on inflator type. Confirm what your maintenance requires. Q5: What’s the correct installation orientation?Install with the white pill facing the inflator cap; it should slide in easily when aligned correctly (do not force it).
