I do not know the pressure rating of the FV, to be honest. When I purchased the FV and requested the custom modifications they knew that I intended to do in-vessel carbonation, so I'd think it could hold at least 20 psi, but there's no way I could guarantee that. The limitation would probably be...
Biggest difference is the lid, which is more substantial, allowing for pressurization of the FV. I had some other ports added. I intended to play around with spunding valves and wanted the ability to use immersion-type temperature controllers with a BCS controller.
I sold my 1bbl plant and don't need a 1bbl FV. It's wasting room in my garage. I want it gone. $700 won't get it sold, but a little beer would grease the wheels to get someone a good deal on a very nice piece of equipment.
Item is still available, but I've got a guy coming to look at it in an hour. Dude is driving quite a ways to cone get it, so either he's a serious buyer or my face will end up on a milk carton later this month.

The Sabco fermenter has a 15.5 gallon liquid capacity. Just like the HLT, MLT, and BK,SABCO's FV is a modified sanke keg.
