One thing to remember, regarding the 212*F number, is the fact that this hose is rated at 1kpsi, 2kpsi, 4kpsi at 212*F...not that 212*F is a magic failure point. I think the temperature rating of the hose would "increase" (within reason) at lower pressures...
And again, I have been running this particular hose for around a year and a half...before that, I had some generic hydraulic hose on for almost two years with the Amsoil setup with no issues other than it was not weather resistant (outer sheath weather checked). I have amassed over 125k miles on hydraulic hose with no ill effect...
