The match will take place on Sunday at New Suez Stadium in Suez City, Egypt. Kick-off is at 20h30.
Pirates, who take a 1-0 lead into the match, left for the North African country on Thursday.
"You have so far not disappointed the nation as has been the norm on your continental campaigns. You are now just 90 minutes away from reaching the Final and as an association we are confident you have it in you to repeat the famous victory we saw at Orlando Stadium last weekend," said SAFA president Danny Jordaan.
"Continue doing your best and hoisting the flag of the country higher. We wish you all of the best and may you return home safe and victorious."
