ISO-KF vacuum components are among the most widely used connection systems in vacuum technology. Their popularity comes from the idea of providing fast, reliable and leak-tight connections while allowing equipment to be assembled, disassembled and maintained with minimal effort. If you are building a new vacuum installation, upgrading an existing system or replacing worn parts, selecting compatible ISO-KF components is essential for maintaining the integrity of the vacuum circuit. At Plasmadiam, we help industrial companies, laboratories and research facilities identify the right ISO-KF components for their application and, when required, install them as part of a complete vacuum system.
The ISO-KF standard (or KF or NW) is commonly used for rough and medium vacuum applications. It defines a family of standardized vacuum connections designed to simplify the assembly of vacuum systems while ensuring repeatable sealing performance. An ISO-KF connection is typically composed of several elements working together. The flange provides the mechanical interface between two pieces of equipment. A centering ring keeps the sealing element correctly positioned. An O-ring ensures vacuum tightness. Finally, a clamp mechanically secures the entire assembly.
Because every component follows standardized dimensions, users can easily connect compatible equipment from different manufacturers. This standardization has made ISO-KF one of the most common connection systems in research laboratories, industrial vacuum installations and testing facilities.
Its modular design also makes maintenance considerably easier. Individual components can be replaced without redesigning the entire installation, reducing downtime whenever servicing becomes necessary.
However, compatibility alone is not enough. Choosing the appropriate diameter, materials and configuration still requires a good understanding of the application. Operating pressure, temperature, process gases and mechanical constraints all influence the selection of vacuum components. For this reason, we always recommend looking beyond catalogue references and considering the complete operating environment before making a decision.
Replacing or installing ISO-KF components may appear straightforward, but achieving reliable long-term performance depends on much more than simply assembling standardized parts. Every vacuum installation is unique. The routing of the vacuum lines, the pumping capacity, the required vacuum level and the surrounding equipment all influence how components should be integrated.
At Plasmadiam, we begin every project by understanding the system itself. Sometimes, the customer already knows exactly which ISO-KF components are required. In other situations, identifying the correct parts is part of our mission. We analyse the existing installation, identify compatibility requirements and recommend components that fit both the technical specifications and the operating conditions. Once the appropriate parts have been selected, we ensure the furniture of ISO-KF Vacuum components and can also handle installation.
Our vacuum technicians ensure that each component is installed according to best engineering practices before the system is commissioned. We also support customers who are expanding existing vacuum installations, because adding new process equipment often requires modifications to the vacuum circuit. Thanks to the modular nature of ISO-KF components, these extensions can be carried out efficiently while maintaining the integrity of the overall installation. Whether your project involves replacing a single fitting or integrating new vacuum equipment into an existing process, we provide the same level of technical attention.
For more than twenty years, we have been helping Swiss companies develop reliable vacuum solutions. Over time, we have learned that successful projects rarely depend on one individual component. They depend on the way every component works together. This philosophy guides our approach to ISO-KF vacuum components.
Rather than simply supplying catalogue references, we help customers understand which parts are appropriate for their specific application. Our consultative approach is particularly valuable when systems combine several vacuum technologies or when installations have evolved over many years through successive upgrades. Our engineering team designs custom vacuum systems adapted to the exact requirements of each project. We work closely with customers to understand their processes before defining the mechanical solution and furnishing ISO-KF vacuum components.
Our expertise extends across applications involving coating, heating, testing and movement under vacuum, allowing us to integrate vacuum components into larger industrial systems rather than treating them as isolated products. Every custom system is assembled and tested in-house by our vacuum technicians before delivery.
