Outer centering ring with inner Ring

ISO-KF seals

Innenring mit Aussenzentrierring

A centering ring ensures the precise alignment and centering of flanges or vacuum components. The integrated O-ring provides an effective seal, preventing air ingress and maintaining the vacuum level. This combination reduces mechanical stresses and facilitates assembly and disassembly by ensuring a reliable and tight connection.

Further information

Overview ISO-KF | DIN 28403
Description: ISO-KF is a quick-connect system widely used in vacuum technology. It consists of symmetrical flanges connected by a clamping ring and an elastomeric/metallic seal.

Sizes: ISO-KF components are available in nominal diameters ranging from DN10 to DN50.

Vacuum Range: ISO-KF is primarily used for coarse and fine vacuum applications, typically up to a vacuum range of 10⁻⁷ mbar.

Usage: Commonly used in laboratory applications and smaller vacuum setups due to its ease of handling and the ability to quickly connect and disconnect components.

Technical Data FPM | FKM

Designation: Fluoroelastomer (FPM)

Temperature Range: -20°C to +200°C

Application Areas: Fluoroelastomer is characterized by excellent resistance to high temperatures, ozone, mineral oils, synthetic hydraulic fluids, fuels, many organic solvents, and chemicals.

Due to its low gas permeability, FPM is suitable for high vacuum applications.

Technical Data NBR

Designation: Acrylonitrile-Butadiene Rubber (NBR)

Temperature Range: -30°C to +100°C

Application Areas: NBR is a standard material for oil- and fuel-resistant seals, wipers, and molded parts for general applications without exposure to ozone or weathering. Various compounds, including those with approvals (e.g., KTW, DVGW, etc.) or fabric reinforcements, can be processed.
