PyraFlat Flanges
|
PyraFlat seals use the ConFlat sealing principle in a rectangular flange. Result: The ease, convenience, and reliability of circular seals are now available for rectangular vacuum seals.
Standard and custom PyraFlat versions have been designed for and used in many applications including high power microwave components and plasma-fusion. Please call our engineering group with your requirements.
