Racking Arms and Gaskets.
I have my racking arms on the cone, about 40 percent of the way up from the bottom. In my next fermenters, I am going to put them on the cylinder. It gives me a way to pull clearer samples for testing earlier in the fermentation process. Also, I have had bad luck with the teflon gaskets. I have had more than one occasion where I loosened the clamp, rotated the arm, and then could not get a good seal because the gaskets have no "spring back" like a BUNA or EPDM. I ended up taking a nice beer shower trying to get the arm back in place and sealed up without an assistant. I suggest purchasing the teflon gaskets that are a "sandwich" with a BUNA center, or just using a BUNA/EPDM gasket. It works. I have not had to use a food grade lube to get the arm to rotate, but that is an option if you find the connection is too sticky.
