iso k flange
The ISO K flange is a standardized vacuum flange component designed for high-vacuum and ultra-high-vacuum applications, providing reliable sealing and connection solutions in demanding industrial environments. This internationally recognized flange system follows ISO 1609 specifications, ensuring compatibility across different manufacturers and vacuum equipment worldwide. The ISO K flange features a symmetrical design with a centering ring and clamping mechanism that utilizes a metal seal, typically made from aluminum or copper, to achieve vacuum-tight connections. Its main functions include creating leak-free joints between vacuum chambers, pumps, valves, and instrumentation while maintaining system integrity under extreme pressure differentials. The technological features of the ISO K flange include precise machining tolerances, corrosion-resistant materials such as stainless steel 304 or 316L, and a knife-edge sealing surface that cuts into the soft metal gasket during assembly. This design enables the ISO K flange to achieve vacuum levels ranging from 10^-3 to 10^-11 mbar, making it suitable for semiconductor manufacturing, analytical instrumentation, research laboratories, coating systems, and particle accelerators. The flange operates effectively across wide temperature ranges and can withstand bakeout procedures necessary for ultra-high-vacuum applications. Available in various sizes from DN 10 to DN 500 and larger, the ISO K flange accommodates diverse system requirements while maintaining standardized dimensions for universal interchangeability, ensuring seamless integration into existing vacuum systems regardless of equipment origin or manufacturer specifications.
