I have not had my kegging system for long but have had a good amount of use from it already. How often should all the o-Rings or small little black seals be replaced? They seem fine now but I would hate to have issues later just because I didn't keep up on the maintenance.

Keep a few spares on-hand. When a keg starts to leak track it down & replace the problem o-ring. A leaky o-ring won't cause too much loss. You can slather some food-grade silicone on a seal to keep it from leaking if you don't have a replacement on hand. Keg-lube (or the generic food-grade silicone) is invaluable.

It's also a good idea to remove, clean and sanitize them before filling a fresh keg.

Check for cracks in the rings also. An obvious clue to change them.

I try to remove all of the fittings clean them and put them back together every time I fill a keg. In reality, I end up doing it every second or third time. So far this hasn't bitten me on the butt, but I know for a fact one day it will.

As for replacing o-rings; I replace them all whenever I get a new keg. From there, I just keep an eye on them and replace any that leak as Dean said above.
