If it is stored in a not too hot place it will probably last much longer
than that on a shelf. I think the problem is if you store it too warm it
seems to start shrinking very slowly so it may not meet the original size
spec, but it should still melt and shrink to the end size. I was given a
box of it that was 'expired' probably 10 years ago and it still seals up
just fine.
Just remember, it is fairly easy to put on, but almost impossible to take
off... and it does require significant heat to properly melt and shrink, the
cigarette lighter you use for plain little shrink tube won't do it, think
more like propane torch or professional heat gun.

ike a good way to go. I just measured a PL-259 shell diameter at about
0.7 inches. I see the shrink rate is about 3:1 so I assume 1" diameter
should work for a PL-259 with RG-213. I also noticed on eBay some
manufacturers state that the shelf life is only about a year or less so it
might be wise to buy just
what you need as opposed to stocking up. I've seen references to 3M and
Molex brands. Any comments/recommendations appreciated. If this topic has
already been beat to death you can reply direct 73, Ron W8RJL email (w8rjl

I've had no trouble using the two sizes of 3m carried by the local
electrical supply. I've been using it for some years and not noticed any
shelf life problems. Some has to be close to 5 years old, or older.
