Assuming there is nothing special about your p traps, go to a home improvement/hardware/plumbing store and buy new ones with new seals. They are inexpensive. Take the old ones with you to make sure you get the right size/length. Too long is ok as they can be cut to length.
You should not need tape on those. But make sure you get the threads straight when putting them on. It is easy to get them cross threaded. The large nuts should turn easily and need only hand tight.
X2 on this advice. Bought one too short, cut it a couple times and it was still too short.
