ISO-KF Vacuum Flange Components: furniture and installation

Vacuum systems rely on many different components, but few are as fundamental as vacuum flanges. They form the mechanical and sealing interfaces that connect pumps, chambers, valves, gauges and piping into a single leak-tight installation. When these connections are reliable, the entire system performs as expected. When they are not, even the highest-quality vacuum equipment can struggle to reach its intended performance. Among the different connection standards used throughout the vacuum industry, ISO-KF flange components have become a reference for rough and medium vacuum applications. At Plasmadiam, we help our customers select ISO-KF vacuum flange components that fit their applications, and we support them from component selection to on-site installation throughout Switzerland.

What are ISO-KF vacuum flange components?

ISO-KF vacuum flange components are standardized connection elements used to assemble vacuum systems quickly while maintaining reliable sealing performance.

A complete ISO-KF connection includes several complementary parts. The flange itself creates the interface between two pieces of equipment. A centering ring positions the sealing element accurately, while an O-ring provides the vacuum-tight seal. The assembly is completed using a dedicated clamp that locks the connection securely in place.

The popularity of ISO-KF technology comes largely from its simplicity. Unlike permanent connections, ISO-KF assemblies can be dismantled rapidly whenever maintenance, inspection or system modifications become necessary. This flexibility makes them particularly attractive in environments where equipment evolves regularly or where frequent servicing is expected. Another of their advantage is standardization. Because ISO-KF dimensions are standardized, compatible components can often be combined across different pieces of equipment, simplifying both installation and maintenance.

We provide systems expertise in equipment manufacture

A wide catalog of verified parts to meet all your needs

Every vacuum system has its own configuration. Some installations require only a few replacement flange components, while others involve complete assemblies for new vacuum equipment or custom-designed systems. For this reason, we offer a broad selection of ISO-KF vacuum flange components capable of addressing a wide range of industrial and laboratory applications.

We want every part supplied to integrate correctly within the existing installation. Before recommending a component, we take the time to understand your project. Are you replacing a worn flange? Extending an existing vacuum line? Building an entirely new installation? Each situation calls for a slightly different approach.

When replacing components, compatibility with the current system becomes essential. Dimensions alone are rarely sufficient to guarantee optimal operation. The overall architecture of the vacuum circuit must also be considered to ensure reliable sealing and consistent performance. For customers developing new equipment, we can also assist in defining the complete vacuum connection strategy from the outset. By identifying the most appropriate flange standard and component configuration early in the project, future maintenance and system expansion become significantly easier.

Our experience in custom vacuum engineering allows us to recommend solutions that remain practical not only today but throughout the entire lifecycle of the installation.

We can also install your ISO-KF vacuum flange components anywhere in Switzerland

Supplying high-quality components is only part of a successful vacuum project. Correct installation is equally important. Even perfectly manufactured flange components may fail to deliver optimal sealing if assembled incorrectly or integrated into a poorly designed system. That is why we also provide installation services throughout Switzerland.

Our technicians install ISO-KF vacuum flange components while ensuring proper alignment, sealing integrity and compatibility with the surrounding equipment. When modifications to an existing installation are required, we pay particular attention to preserving the performance of the complete vacuum system rather than focusing on the individual component alone.

This global vision reflects the way we approach every project. With more than twenty years of experience in vacuum engineering, we know that reliable systems result from the combination of carefully selected components and thoughtful integration. Beyond component supply, our engineering team designs custom vacuum systems adapted to each customer’s application. We collaborate closely with our clients to understand their processes before developing mechanical solutions capable of supporting applications involving coating, heating, testing or movement under vacuum. Every custom system is assembled and tested in-house by our vacuum technicians before delivery.

Whether you require a single ISO-KF flange, a complete vacuum connection package or the installation of a custom-designed vacuum system, we support your project with the same objective: providing durable, reliable and technically appropriate solutions that contribute to the long-term performance of your equipment.
