G-1325 Copper Gaskets

G-1325 Copper Gaskets – High-Vacuum Flange Seals for UHV Applications

The G-1325 copper gaskets are precision-formed seals designed for use with CF (ConFlat) vacuum flanges. These annealed copper gaskets provide leak-tight seals under extreme vacuum conditions and are ideal for ultra-high vacuum (UHV) and high-vacuum systems found in research, semiconductor, and industrial applications.

Key Features:

• Model: G-1325

• Material: High-purity, oxygen-free annealed copper

• Outer Diameter: Designed to fit standard CF flange sizes (typically 2.75″, 4.5″, etc.)

• Seal Type: Knife-edge compression for reliable UHV sealing

• Usage: Single-use to ensure maximum vacuum integrity

• Vacuum Range: Suitable for UHV conditions below 10⁻⁹ Torr

• Temperature Tolerance: Up to 450°C in vacuum systems

Common Applications:

• Ultra-high vacuum (UHV) chambers

• Research laboratories and physics experiments

• Semiconductor process systems

• Cryogenic and high-temperature vacuum seals

• Surface science and electron microscopy
