I bought several used scepter fuel cans 5 or so years ago and added the viton gasket and red retaining strap. A few days ago I was out re-treating my stored gas with pri-g when I noticed that with one can that was empty apparently atmospheric pressure had crushed the sides of the can in, resulting in some pretty severe cracking on the side. It didn't crack all the way through but I have discarded that can and am thinking about getting rid of the other cans from the same purchase.
From JAGMTE:
In regards to the cracked can, that would be the first one I have heard of cracking. The cans are molded using Polyethylene which is extremely resistant to cracking, in fact it is not possible to crack a newer or well maintained can so the crack would indicate that at some point in its service life it was exposed to the sun and or a heat source for a very long time. Clearly it is a serious risk to use the cracked can.
So the earlier poster might want to reconsider leaving them in the sun all the time for years.

I think I found a confirmation that gas and diesel can use the viton seal but the rubber seal is diesel only.
