A few thoughts while reading this thread.
The "Sanitary" ball valve offered by Brew Magic. No ball valve is truely sanitary. There is always a void between the seat and the valve body for media to get trapped, even if you use cavity filler seats, which this ball valve probably does. What that means is that you need to disassemble & clean after every use. The only true sanitary valves are sanitary butterflys & sanitary diaphragm valves. Just a note to beware if you think these valves don't need to be cleaned.
For those having problems with the o-rings on the CPC couplers, look into replacing the o-rings with Viton, which Mc Master should have in stock. I believe the standard ring is Buna-N which has a max temp rating of between 180dF & 220. Viton has a higher rating, about 285dF I think.
