Varian 1.5″ Vacuum Flange

The Varian 1.5″ ConFlat Vacuum Flange is a precision-engineered stainless steel flange designed for high and ultra-high vacuum (UHV) applications. Utilizing a knife-edge sealing mechanism and copper gaskets, this flange delivers leak-tight performance down to 10⁻¹³ Torr, making it ideal for scientific, semiconductor, and industrial vacuum systems.

Key Features:

• Flange Size: 1.5″ (DN16CF)

• Material: 304L stainless steel (UHV-compatible)

• Seal Type: Knife-edge metal seal with copper gasket

• Vacuum Range: Atmosphere to ≤ 10⁻¹³ Torr

• Configuration: Available in rotatable or non-rotatable versions

• Mounting: Through holes or tapped holes depending on model

Engineered for reliability and thermal stability, this compact flange is commonly used in vacuum feedthroughs, viewports, and instrumentation ports in UHV chambers.
