CF Seals & Gaskets – Essential for Leak-Tight Vacuum Connections

When it comes to ultra-high vacuum (UHV) systems, the right gasket makes all the difference. Our ConFlat (CF) seals and gaskets ensure a perfect, leak-tight connection between two CF flanges, even under the most demanding conditions.

Why CF Gaskets Matter:

• Compatible with nearly all feedthroughs and fittings in our range.
• Designed for high vacuum and UHV applications with matching outer dimensions.

Copper Gaskets

• OFHC Copper (Oxygen-Free High Conductivity): Delivers a vacuum-tight seal up to 10⁻¹³ mbar, even after repeated bake-outs at 450 °C.
• Silver-Plated Copper: Prevents oxidation at high temperatures for extended life.
• Annealed Copper: Requires less sealing force—ideal for fragile components like zero-length viewports, gauge heads, and ceramic feedthroughs.

Viton Gaskets

• Low Outgassing: Degassed to reduce outgassing from 10⁻⁷ mbar·l/sec to 10⁻¹⁰ mbar·l/sec.
• Long-Term Performance: Store in a dry atmosphere to maintain benefits.
