Typically hoses have a burst rating of 4x working pressure.
Were these rated the same way?
“Typically hoses have a burst rating of 4x working pressure...”
I now do not remember the safety factor, though it was much higher than 4X WP. It is specified in the Mil-Spec, but I no longer remember the number...
Rather ordinary hoses would have a 4X WP safety factor.
Experimentally I made a braided hose in such a way that the yarns were locked so that they could not work together as they are supposed to do - the hose burst at a fraction of rated pressure. So much for that mfg idea...
