Some of the fitting barbs were made of steel also.

Readings are too high. Spray the condenser with a water hose while monitoring the high side pressure. Does it drop like a rock? If so, start by checking airflow across condenser. Check the cooling fan also. If the high side drops, does the low side drop also?

You need to be careful with aftermarket fans. Some of them allow you to wire them in reverse rotation. Some of them mount with different types of mounting that will allow them to rub on the condenser and radiator. Some of them do not have the proper CFM ratings.
