Further information

Overview of 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 Stainless Steel | 1.4301

Stainless Steel 1.4301, also known as V2A steel or AISI 304, is a commonly used stainless steel grade with excellent corrosion resistance properties. It is resistant to moisture, humidity, and mild chemical environments, such as water and diluted acids. Additionally, it offers good weldability, high strength, and wide applicability in various industries, including food processing, the chemical industry, and construction.

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.
