The Ferro Flange has become a standard mount for rough vacuum and midrange vacuum applications, such as vacuum coating, laboratory, and front-end semiconductor processing. It provides a Viton O-ring and clearance holes for mounting screws.
The ConFlat flange is an industry standard flange generally used in high- and ultra-high vacuum systems, in applications such as critical coating, UHV semiconductor processes, and advanced research and other leakage-critical equipment. It provides standard geometry including a knife edge for use with a metal gasket (not included), and clearance holes for mounting screws.
The ISO flange is an industry standard flange intended for flange-to-flange (piping), or flange-equipment installations. Individual external clamps (not included) in contact with the flange compress the gasket in its centering ring (not included), to seal between the feedthrough and the mating component.
