Eric,
Sounds like you will be in good shape.... remember that the orings are to be lightly coated with new refrigerant oil.... or that higher viscosity stuff ...and that it comes in two colors .... to match the frigerant you are using..... refrigerant oil to be put into the compressor should be left sealed until the last minute..... at the time you are about to start the vacuum process.... almost impossible to get moisture out of the oil .
