Used in manufacturing or engineering processes where precise positioning is required under vacuum conditions..
This could be in applications such as semiconductor manufacturing, optics assembly, or any high-precision part handling requiring vacuum control.
Often made from materials that can withstand vacuum conditions without out grassing, such as stainless steel, aluminium EN1.4301, EN1.4404
Designed to maintain airtight seals when placed in a vacuum environment, preventing leaks that could compromise the integrity of the vacuum chamber.
