Vacuum Clamp - KF Flanges assembile: KF clamp or nail clamp

Feature : 
*Hinged Clamp assemblies, detailed above, are the most commonly used method for making KF-Flange vacuum seal connections. Assembly is simplified by the 360 degrees rotatable flanges and self centering feature of the centering ring. 
*Pressure is applied uniformly around the 15 degrees outer surface of both flanges by finger-tightening the single wingnut until the first metal-to metal contact is made between the spacing lips of the centering ring and the inner surface of the mating flanges. This compresses the O'ring between the flanges and makes the vacuum seal.  

Specifications :  
*Metail : Aluminum  
*Surface Treatment: Nickel Plating  
*Type: KF16 ~ KF50
