If you are talking about the mating surface where you attach the regulator to 
the CO2 cylinder, get a nylon/fibre washer to seal this connection. You can 
get these at welding supply or auto parts stores. Take along your regulator 
to get the proper size.
If you are talking about a pipe thread connection, disassemble the leaking 
connection and clean the threads. Apply a thread sealant and retighten.

Personally, I do not like the thread tape style of pipe sealant, I prefer the 
liquid Teflon. Thread tape tends to not stay on the threads. Small pieces 
tear off when tightening and are cause for concern where they end up. They 
can get lodged in your regulator, valves, orifices, tubing or any other 
component in your CO2 system.

Sorry for the other post on diagnosing the leak being late. I am catching up 
on unread digests. :(
