So what I figured was correct, the port on the top of the 1st stage is a low pressure port? If so, what would one use that port for? Thanks!!
On the MK25 the 2 HP ports are located either side of the first stage, next to the yoke or DIN, and clearly marked "HP." The LP ports (x5) are on the swivel turret.
The HP port thread size is different from the thread size of the LP ports - your Oceanic transmitter will not fit on a LP port. The reason there are so many LP ports is to give the user many options/combinations for hose routing for diving single and double tanks.

Ok great, now is there any recommendation on how tightly one should install the transmitter?

Hello, I just got the VT Pro as well... the instructions recommend using Christo-Lube MCG111 grease on the O-ring seal... is there any equivalent types... it says this is a halocarbon based grease...that's just normal grease isn't it? My LDS options here in Qatar are more than a bit limited but I want to make sure I get a good seal on the transmitter/HP port... I looking forward to diving with it this weekend. Thanks in advance for any assistance
Don't even worry about any lube... Just screw it in as tight as you can hand tight, then give it just a bit past that with a thin wrench. Not moving probably more than noon to 1 with the wrench. Just enough so it doesn't back out if you bump it.
Everyone gets all worried about whether to lube that o-ring on the transmitter, or on any hose. Think about it for a second, the o ring there is screwed in to place where it cannot move - and it goes in there and stays... Maybe come out once a year.
The pressure on a tank o-ring is exactly the same pressure, and that gets regs and fill whips tossed on it 2 or 3 times a day, people unscrewing yokes before the bleed lines, etc... and yet that o-ring on a tank gets no lube and lasts for hundreds of times off and on.
