Description: ISO-K is a flange system similar to ISO-KF, but designed for larger diameters. The connections are sealed with clamps and elastomer/metal gaskets.

Sizes: ISO-K components are available in larger nominal diameters than ISO-KF, typically starting from DN63 and larger.

Vacuum Range: ISO-K can also be used for rough and fine vacuum applications but is robust enough for applications up to high vacuum levels (10⁻⁸ mbar).

Usage: ISO-K is often used in larger vacuum apparatuses where more stable and larger connections are required.

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.

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.
