Look at the bottom of the description
Manufactured from 304-type stainless steel with a polished finish. 1.5" tri-clover connection. You will need (2) 1.5" tri-clover clamps, (1) 1.5" teflon gasket, (1) 1.5" EPDM gasket, a 1.5" tri-clover butterfly valve, and of course a tank full of wine or beer with a tri-clover ferrule (fitting) welded on!
You would weld a TC fitting to your fermenter. The left side of the racking arm (as pictured) would pass through the fermenter fitting into the beer. The valve obviously goes on the outside.
Pretty expensive compared to a racking tube, though.
