🔸 Ceramic Beads & Spacers – Flexible Insulation for Vacuum & Air-Side Wiring

Also known as fish-spine beads due to their interlocking, flexible design, our ceramic beads and spacers are the ideal solution for insulating bare electrical wires in both vacuum and air-side systems.

Crafted from high-purity alumina, these short cylindrical tubes feature one concave and one convex end, allowing them to link together seamlessly. This design provides continuous electrical insulation and effective shielding for central conductors, even in tight or curved configurations.

🔧 Key Features:

• Flexible, interlocking design for custom wire routing
• Excellent thermal and electrical insulation
• Suitable for UHV environments
• Made from high-purity alumina for durability and performance

Perfect for use in scientific instruments, vacuum chambers, and high-temperature setups where precision and reliability are essential.
