UHV Flanges (Ultra-High Vacuum)

Our Ultra-High Vacuum (UHV) flanges are engineered for demanding vacuum environments and are widely used in vacuum chambers, research systems, semiconductor manufacturing, and particle physics applications.

Key Features

  • Standards Available: CF (ConFlat), ISO-K, ISO-F, and KF (NW) flanges compatible with global vacuum systems.
  • Sealing Method: CF flanges utilize metal gaskets (e.g., copper) for leak-tight, all-metal seals down to 10⁻⁹ mbar or below.
  • Connection Types:
    • CF: Bolt-fastened for secure, high-integrity connections.
    • KF / ISO: Quick-clamp connection with elastomer O-rings for ease of assembly.
  • High Precision Machining: Smooth sealing surfaces (Ra < 0.4 µm) ensure excellent leak tightness and repeatable performance.
  • Material Options: Made from high-quality stainless steel (304L or 316L), with optional vacuum degassing, deuterium cleaning, or annealing for ultra-clean applications.

Applications

Ideal for UHV systems in surface science, thin film deposition, electron microscopy, ion implantation, and other ultra-clean or high-temperature processes.

Customization

Custom sizes, flange drilling patterns, and material grades are available upon request to match your system requirements.

How to Order

Please provide the following details:

  • Flange type and size (e.g., CF40, KF25)
  • Material preference (304L, 316L, etc.)
  • Surface finish or treatment requirements (if any)
  • Quantity and delivery timeline

We will respond with a quotation and technical datasheet. All flanges are precision-manufactured and vacuum-ready.
