I have found at least four inflator hoses (over about 10 years) that had
inadequate crimping but not no crimping.  The poor crimping allowed the
hose to twist on the fitting.  With the proper tool or a home made
crimping device these can be made safe but of course we should not have to
do this and the manufacturers need better QA

that didn't click at that time. I thought maybe it was some different method of
crimping. The hose had actually lasted through one dive, and didn't blow until
I was at the very end of a second one.

odd-looking crimps, they may want to look closer.
