I can fit 5 kegs in my keg fridge, but I only have a 4 valve manifold.

I have one of those keg connection manifolds with a brass stopper plug on the end (opposite the end where the gas comes in, which I think is for expansion (adding another manifold section).

My question is this: Couldn't I just install another valve on the end instead of that plug, and convert it to a 5 instead of just a 4?  Thanks for any advise.

Maybe. Check with the manufacture of your manifold. They may have the parts you need.

You can do anything you want. Use the plugged port or add wyes and tees to any of the other ports or valves. Nothing sacred there.

Your only limits are imagination, bore size and thread cut.  My 4 port manifold is setup the same way.  I've never taken the end plug out but it looks like it is the same size and threaded the same as the ports on the front of the bar.

You can add additional line or a secondary regulator and other things my barely awake brain can't think of at the moment.

I did this to turn a 3 into a 4. The end plug has the same threads.

no problem doing this.  The plug is the same thread as the other ports.

teflon Tape all connections... and put shutoffs with check valves to make sure the air pressure of the kegs are isolated.  (otherwise a leak in one, or a pull off of the other kegs... leaving 5 flat kegs. 

I put 6 into my fridge, and put two other ports (one for my beer gun, and one for a keg outside of the fridge for times when I needed to pressurize before storing)

The other option is to get another two port or more maifold and connect it to the plug port.

Just make sure if you have taps out the front of the fridge, you look to see if you have spaceing for it.   I put 6 kegs into my fridge, bought 6 taps... and just did not have a wide enough front on the fridge to make it look good.  (So I only have 5 on tap through the door)
