I researched this issue a while back and came to the conclusion it was not possible, but I thought I'd give it one more shot. My old Genisis HP 80s have the 7/8 angled DIN valve. They are great small form tanks for beach dives but, because of the angle my Kraken, et al.. don't fit so good. Does anyone make a straight 7/8 valve?
