These fittings for the bottom dump and racking arm offer unparalleled cleaning and sanitation advantages over its NPT brother. The tri-clamps can be broken down and taken apart with ease, as the seals are made via o-rings, not threaded joints. No need to wrap and rewrap with pipe thread! Blichmann takes pride in using only 304 stainless steel, and the interior all-weldless construction can't be found anywhere else on the market today!
