The ends (fittings) of a hydraulic hose have both inner and outer metal parts. The flexible "rubber" hose is crimped or "squeezed" between them. How can the inside collapse if there is an inner metal lining at the ends? You are suggesting that the inner metal part no longer is able to keep the "rubber" from collapsing?

This isn't making any sense to me.

Please look for that photo, Dan, as it might have some clues to this weirdness (at least for me it's weird...).
