I'm gonna build a pressure reducer sys for testing rads with a lab quality PSI gauge for just before the inlet nozzel this will never happen agin . testing will be done @ 8 psi from now on ...

but that's what i get for being too lazy to get a razor to cut off the hose from the barb ,grabbed what was next to me "the sissors" that i was cutting the hose with & stabbed the Rad right off
