At the start of every boating season, do a full inspection of your PFD, including the cylinder’s date and condition. Also, store your PFD in a cool, dry place—not in a hot car trunk or damp basement. Extreme heat and cold can shorten the cylinder’s lifespan. Think of it like a vampire: keep it out of direct sun and away from moisture, and it’ll last longer.
The Little Plastic Tab
You know that small, green or yellow tab on your inflator? That’s the indicator—it shows if the cylinder is still sealed. If the tab is missing or broken, the cylinder might have been partially discharged. Replace it. Also, check the O-ring on the inflator—if it’s cracked, dry, or missing, new cylinder or not, you’ll get a leak. A tiny rubber ring is cheap insurance.
