Technical Information
CF flanges operate based on a metal-to-metal sealing principle.
A soft metal gasket—typically OFHC copper—is compressed between flange faces under applied torque, plastically deforming to form a permanent, leak-tight seal.
This design ensures low gas permeability, high mechanical strength, and repeatable vacuum performance.
Nitrosis CF flanges provide durable and dependable performance in both laboratory-scale and industrial vacuum systems, ensuring consistent sealing integrity over long-term use.
