Is the condenser above or below the a coil?
what size are the fittings coming from the unit?
The install manual will have that info in it.

If you don't have the install manual. Post brand and model number of your condenser.

Some brands use a different size then other brands for the same efficiency.
Check your manual, but I'll bet it calls for a 3/8" and 7/8".
