No, the product is rated for 160 degrees continuous and 180 intermittent temperature only.

where is the leak? if between the threads of connector to HWH male, then verify you used plumbers tape (Teflon) to seal the threads before installing the connector. Using bare will leak. If the leak is on the hose, I can guess it may be the crimped area of the hose female connector (assuming you're using a female-female ended hose). This is not a quality product I've found to my disappointment 2x now!
They all had red, water heater had hot and cold identified so it wasn’t a concern to me.
