FlyMeAway,
Thanks for the info on the West Marine!
The West Marine pfd is 4.5 years old now and I inspected it over two years ago. I spoke to West Marine today trying to get the correct Leland rearming kit after doing an inspection on the pfd this morning. Per West Marine, the date on the yellow bobbin is the date of manufacture rather than an expiration date. The bobbin was in pristine visual condition but I’m replacing it anyway. I ordered 3 additional spare bobbins as well. I’ll keep the old CO2 cylinder and one well sealed new bobbin as an emergency spare. The old CO2 cylinder gross weight exceeds it’s minimum weight of 140 grams per the decal on the cylinder so it’s still good to use.
Thanks again!
You're quite welcome! I'm going to give you info overload on bobbins, hope that's ok. FYI, the OEM for nearly all of the bobbin-activated, bayonet-style inflators is Halkey-Roberts, regardless of who makes the vest.
The Halkey-Roberts inflator bobbins used to packaged with a manufacturing date and a shelf/in-use life. Originally, most bobbins for recreational use had three years on the shelf and then three more years once in service, for up to six years total at the max end. Then at some point the Leland bobbins sold by West Marine went to three years total from date of manufacture, though Leland bobbins I'd purchased elsewhere still had the 3+3 labeling.
There are newer Halkey-Roberts bobbins that are supposed to be labeled with an extended five-year simplified life from date of manufacturing. Landfall currently sells these:

In case you really want to geek out on this, here's the Halkey-Roberts sheet on the bobbins:

Note that the shift to 5-year bobbins is so recent, even Halkey-Roberts' materials don't fully reflect it. For example, the servicing instruction sheet for their inflation mechanism (

Note that Leland brands bobbins, but (at least to my knowledge) Leland doesn't actually manufacture them. Leland does make the gas cylinders, however (they're one of the largest US manufacturers of those), and so at some point they got into the complete rearm kit business.
