The Blank Off Flanges - Nonrotatable are available in the following sizes: CF 16, CF 35, CF 63, CF 100, CF 150, CF 200, CF 250, CF 300, CF 350. They are made out of Stainless Steel.
The high sealing and the low leak rate performance of the CF Flange connection is due to the gasket material.
When the CF Flange is correctly assembled, the knife edge is compressed onto the flat copper gasket forcing the seal material outwards to the flange. The gasket is entirely enclosed and will not edge out even under the highest bakeout temperatures.
The CF Flange is offered in both rotable and nonrotatable versions, with through holes, or tapped bolt holes.
