Add another season of work to your Stearns® inflatable life jacket when you recharge the activation hardware with a Stearns® Rearming Kit 38MRK (#0951). This kit includes a 38-gram CO2 cylinder with bayonet tip that's specially-designed to fit life jackets made especially for this kit number, as well as step-by-step rearming instructions. Check your life jackets’s owner’s manual for the rearming kit that matches your PFD - it may be unsafe to substitute another design.
