Category: KF Seals

Ensure a perfect seal every time with our KF Centering Rings, designed for precise alignment and secure fastening between KF flanges. Each ring features an enclosed O-ring and clamp system that guarantees leak-free connections, even in demanding vacuum environments.

🔩 Wide Range of Sealing Materials
Choose the right seal for your application:
Aluminum, Copper, EPDM, FFKM, Kalrez, Neoprene, Perbunan, Silicone, Teflon, Viton – each offering unique benefits in terms of temperature resistance, chemical compatibility, and gas permeability.

🌡️ Elastomer Seals
Flexible and easy to install, elastomer seals are slightly gas-permeable. After evacuation, gas flow stabilizes, making them ideal for many standard vacuum setups.

🔥 Metal Seals for Extreme Conditions

• Aluminum Seals: Temperature range –196 °C to +150 °C
• Copper Seals: –196 °C to +200 °C (up to +450 °C with silver coating)
  These single-use seals are perfect for UHV and high-temperature applications, and require special high-force clamps for secure installation.

Whether you’re building a new vacuum system or upgrading an existing one, our KF Centering Rings offer the performance, flexibility, and reliability you need.
