Plasma is used to increase the surface energy of many materials with high efficiency

Our KF to Tube Fitting Adaptors follows ISO-KF international standards

These ball valves have an NW-KF vacuum flange for connection to the vacuum system

CF4.50" (DN63CF) Plate Nuts Non-Rotatable Vacuum leak rate: Typically 1x10-5mmHgPlate nuts are for clearance (through hole) CF flanges. They are metal plates with 2 threaded holes, shaped to match the corresponding CF flange's bolt hole patterns and replace the individual nuts. The plate nuts major advantage is, once two bolts are manually started, the plate nut acts as its own backing wrench and washer, the bolts are tightened using one wrench.
