The flange sizes you mentioned involve two different standards commonly used in vacuum systems: ISO-KF (also known as NW, or Klein Flange) and Conflat (CFF, or Copper Gasket Face).
ISO-KF NW-25 is a flange size specified by the ISO-KF standard. It has a nominal diameter of 25 millimeters (mm) or approximately 1 inch. ISO-KF flanges use a clamp and elastomeric O-ring seal to create a vacuum-tight connection. This type of flange is commonly used in low to medium vacuum applications.
On the other hand, Conflat (CFF) flanges are used in high vacuum applications. The size you mentioned, 2.75 inches, refers to the nominal inner diameter of the Conflat flange. Conflat flanges feature a knife-edge sealing mechanism, where a copper gasket is placed between the flanges and tightened to create a vacuum seal.
The fact that you mentioned "in stainless steel" indicates that you are referring to the material used for the flanges. Stainless steel is a common choice for vacuum flanges due to its high strength and excellent corrosion resistance.
So, in summary, the statement "Flange Sizes ISO-KF NW-25 To Conflat CFF 2.75 In Stainless Steel" refers to a transition or adapter piece that enables connecting a vacuum system with an ISO-KF NW-25 flange to a Conflat CFF 2.75-inch flange. The flanges are made of stainless steel, which is a suitable material for vacuum applications.
