Question about hydraulic line crimping methods

I was doing a repair on a 5-story bank building and tried using a hand-crimper on the new hose, but the fitting leaked after a week. Switched to a bench-mounted crimper from the shop and it's held perfect pressure for over a month now. Anyone else find the bench tool is the only way to get a reliable seal on those high-pressure lines?

Our shop's bench crimper has never failed on lines over 3000 psi.

Yeah, but that's wild to me. I saw a post last week where a guy's bench crimper blew out a ferrule on a 3500 psi line, ruined a whole day's work. He swore it was rated for that pressure too. Makes you wonder if some shops just get lucky with a really good unit, or if others are pushing things past the safe limit without even knowing.
