- Stable to 350°C
- Durable, leak-tight
Graphite Ferrules
- Preconditioned to eliminate outgassing
- High-purity, high-density graphite
- Smoother surface and cleaner edges than conventional graphite ferrules

- Stable to 450°C
Vespel/Graphite Ferrules
- VG2, 60% Vespel/40% graphite blend offers the best combination of sealing and ease of workability
- VG1, 85% Vespel/15% graphite blend offers equivalent composition to Agilent Vespel/graphite ferrules
- Seal with minimal torque, reusable, and preferred for vacuum and high-pressure uses
- Stable to 400°C
