ISO

Thermionics ISO flanges provide reliable, repeatable sealing for ultra-high vacuum (UHV) and high-vacuum systems in research, manufacturing, and analytical applications. Designed to meet ISO 1609 and related standards, these flanges offer quick, secure assembly using a centering ring and clamp system, reducing installation and maintenance time. ISO flanges are ideal for applications requiring frequent assembly/disassembly, large-diameter connections, or compatibility between different vacuum components. Proven in both laboratory and industrial environments, Thermionics ISO flanges deliver the leak-tight performance required for demanding vacuum operations.
