ISO-KF Flanges For Vacuum Systems

ISO-KF flanges are a fundamental design element of vacuum piping systems, intended for connecting and joining individual components. Our range includes variants with high-quality steel tubes available in various lengths – short for compact installations and long for applications requiring greater reach or flexibility.

Each flange is manufactured with high dimensional accuracy according to ISO 2861 and DIN 28403 standards, guaranteeing:

  • compatibility with all standard ISO-KF components (clamps, seals, blanking flanges, etc.)
  • a reliable and leak-tight connection without the need for complex assembly
  • durability and a long service life even under demanding operating conditions

Thanks to their robust construction and precision workmanship, ISO-KF flanges are used in both laboratory systems and industrial operations – for example, during vacuum pump service and maintenance, pipe assembly, or technical gas distribution.
