vacuumpassen

Vacuumpassen is a term used in vacuum technology to refer to fittings and adapters that connect vacuum lines, tubing and chambers to create sealed, leak-tight connections. They are essential for building and maintaining vacuum systems across laboratories, manufacturing and research settings.

The category covers a range of components, including quick-connect couplings, barbed fittings for tubing, threaded adapters (such as NPT or BSP), and flange systems (for example KF/ISO-K flanges and ConFlat CF flanges). Materials commonly used are stainless steel, brass and various plastics, chosen for chemical compatibility and vacuum performance. O-rings and gaskets in Viton, Buna-N or other elastomers are typically used to ensure a tight seal, and may be combined with lubricants suitable for vacuum service.

Standards and configurations vary by application and vacuum level. KF and ISO-K flanges are widely used for moderate to high vacuum systems, while CF (ConFlat) flanges are preferred for ultra-high vacuum. The selection depends on required vacuum level, chemical compatibility, temperature, system geometry and ease of assembly or disassembly. In high-precision or clean environments, cleanability and material purity are important considerations.

Applications span many industries, including scientific research, electronics manufacturing, pharmaceutical production and food packaging. Correct selection ensures reliable performance, minimal outgassing and reduced leak risk. Installation and maintenance involve proper cleaning, correct torque or clamp usage, compatible lubricants, and regular leak testing, often with helium or other tracer methods to verify integrity.

In summary, vacuumpassen comprise the connectors and adapters that enable secure, adaptable and leak-conscious interconnections within vacuum systems, supporting a wide range of industrial and research applications.
