Mustang® Replacement PFD Bobbins

Bobbins are a replacement part for all Halkey Roberts type automatic inflators. They dissolve when immersed in water and cause the CO2 cylinder to inflate the PFD. Mustang® recommends annual maintenance and inspection of your Automatic Inflatable PFD. For recreational use, bobbins should be replaced every three years to avoid inadvertant inflation. Package of 1.
