Vacuum-System Equipment Hub
Feedthroughs, Magnets
& Vacuum Fittings
Explore the interfaces that carry power, signals, cooling, gas and motion across the vacuum boundary—plus magnetic source hardware, flanges, adapters, fittings, manifolds and chamber connections used throughout high-vacuum coating systems.
Transfer Through the Vacuum Boundary
The hardware that connects the process inside the chamber to everything outside it
A vacuum chamber still needs electrical power, sensor signals, cooling water, process gas, mechanical motion and service access. Feedthroughs and fittings transfer those functions through a sealed boundary, while flanges, adapters, plates and manifolds connect pumps, valves, sources and process hardware without compromising vacuum integrity.
Magnetic assemblies add another critical layer. Beam-bending magnets, sweep coils, source magnets and related hardware shape or move energy inside deposition equipment and must work with the source geometry, power supply, cooling and controls.
