However, when running nmap on them, one betrays the port that SSH is running on, and the other does not. I have shut down iptables on both machines and the behaviour remains this way. What could be the cause?
You're probably not running a full port scan with nmap. One of the systems is using a port that nmap includes in its quick scan set, and the other does not.
Specifically, how can I hide the port that SSH is running on?
You can't. If that port is open, a full nmap scan will reveal it.
