Bellow with flanges, L = 500mm, DN100ISO, stainless steel 316L

ISO-K Corrugated Bellows – Ultra-Flexible Connections for Vacuum Systems

Our annealed flexible hydroformed bellows, also known as ISO-K corrugated hoses with flanges, are designed to deliver exceptional flexibility and durability in demanding vacuum environments.

These bellows are available in standard inner diameters from 63 mm to 160 mm, and offer reliable performance whether annealed or not. For extreme flexibility, the bellows can be soft-annealed, enhancing their ability to handle tight bending radii and dynamic movements.
