I understand your frustrations. I would NEVER use a barbed fitting for 100 PSI, it's crazy. It's just engineers being pushed by the company to save a nickel on each unit. I see this exact thing with the analyzers I work on. Our Nox analyzer used to use Swagelock fittings inside but since the new "improved" analyzers with barbed fittings inside came out we have nothing but leaks.
