Stainless Steel Hose with Small Flanges

Flexible stainless steel hoses with small flanges offer highest tightness and mechanical stability for demanding high vacuum applications. With leak rates of 1 × 10⁻⁹ mbar l/s, they are the ideal solution for professional vacuum systems in laboratory and industry where absolute reliability and longevity are required.

Highest Tightness for High Vacuum

The stainless steel hoses with KF small flanges achieve leak rates of 1 × 10⁻⁹ mbar l/s, ensuring absolute tightness even in the most demanding high vacuum applications. The standard-compliant small flanges enable quick, safe and reproducible connections to all common vacuum components.

Flexibility Meets Robustness

Despite their high mechanical stability, the stainless steel hoses offer sufficient flexibility for easy installation and adaptation to different system configurations. The corrugated stainless steel profile combines flexibility with pressure resistance and reliably prevents collapse under vacuum.

Versatile Nominal Widths and Lengths

The stainless steel hoses are available in nominal widths KF DN 10, 16, 25 and 40 mm as well as in various lengths from 250 mm to 1000 mm. This enables precise adaptation to your specific requirements and system dimensions.

Application Areas

High vacuum pumps and turbomolecular pumps Analytical instruments and mass spectrometers Coating systems and sputtering systems Vacuum chambers and recipients Research and development laboratories Semiconductor and thin film technology

Corrosion Resistant and Durable

Stainless steel offers excellent corrosion resistance and is virtually maintenance-free. The hoses are chemical resistant, temperature stable and designed for continuous operation in professional vacuum systems.
