Wire seal Copper gasket (1) flange COF-900

Wire Seal Ultra-High Vacuum Sealing for Bell Jars & Custom Chambers

Designed for demanding vacuum environments, our Wire Seal Flanges are the go-to solution for bell jars and custom-built vacuum chambers. These flanges feature a male and female interface that compresses a 0.080-inch diameter OFHC copper wire, forming a leak-tight seal down to 10⁻¹³ mbar—even after repeated bakeouts up to 450 °C.

Enhanced with OHFC copper gaskets, these flanges offer exceptional compatibility with UHV conditions and process chemistries, ensuring long-term reliability and performance.

Key Features:

• Leak-tight sealing for ultra-high vacuum systems
• Resistant to high-temperature bakeouts
• Ideal for custom vacuum chamber designs
• Compatible with aggressive process environments
