Edge welded bellow with DN160ISO-K flanges, L = 258 – 108mm, ID = 150mm

Edge-Welded Bellows – Ultra-Flexible ISO-K Connections for Dynamic Vacuum Systems

Our edge-welded bellows, also known as ISO-K flex metal bellows, are designed for high-flexibility applications where movement and adaptability are essential. These stainless steel bellows allow for axial, lateral, and angular motion, making them ideal for dynamic vacuum setups.

Unlike hydraulically formed hoses, edge-welded bellows naturally spring back to their neutral length—typically midway between their extended and compressed states—when not under vacuum. This self-centering behavior enhances system stability and reduces mechanical stress.

🔧 Key Features:

• Highly Flexible Design for multi-directional movement
• Bakeout Temperature: Up to 250 °C
• Not rigid bodies, but capable of overcoming a defined working stroke
• Ideal for use as flexible connectors between vacuum flanges or end fittings
